We just got the information from a Twitter user – Adam, that the AT&T MMS Carrier Update is out on iTunes!
Apple has issued a support article explaining the process for activating MMS. You should update to iPhone OS 3.1 if you have not already done so, and then click the “Update Settings” button on the pop-up window notifying them that a new carrier settings file is available.
One problem for iPhone OS 3.0 is about the battery life. Some users reported that the battery life is degraded after upgrading to iPhone 3.0.
As you all know, Apple has released iPhone OS 3.1 few days ago. However, in the release note, it doesn’t mention any bug fix or improvement about the battery life. Despite of this, I’d like to check with you:
Is the battery life improved on iPhone 3.1? For me, it seems like a little bit better. I haven’t performed any serious test on it. It’s just my first impression after the upgrade. So, how about you?
This guide and tutorial will show you how to jailbreak your iPhone 3G running firmware 3.1, using PwnageTool for Mac OS X. So far, only PwnageTool is available for jailbreaking the 3.1 iPhone 3G and it is only for Mac. I believe a RedSn0w method for both Mac and PC will be available soon.
1. Make sure you have installed the latest version of iTunes (iTunes 9).
2. On your desktop, create a folder called “jailbreak” or whatever name you want to give it. It doesn’t really matter. Download PwnageTool 3.1 and the 3.1 IPSW (iPhone1,2_3.1_7C144_Restore.ipsw) from here and save them into the “jailbreak” folder. Note that you should download the firmware using FireFox as Safari often brings up issues. Also note that the PwnageTool download link is a torrent and you will need a torrent downloader (ie. uTorrent) to download it.
3. Launch PwnageTool. It will give you some sort of warning. Just click OK. On the next screen, choose the “Expert Mode”.
4. Select your iPhone model and click the blue arrow to continue.
5. Browse for the IPSW you downloaded in step 2. You should then get a green check mark.
6. You will now be offered several options. Choose “General”. Make sure the “Activate the phone” box is left UNCHECKED. This is very important. I repeat: make sure the “activate the phone” box is blank.
7. Increase the root partition size to 700 MB. This is not necessary but it is safer. Then click the blue arrow to continue. Click the blue arrow one more time to skip the bootneuter settings, which aren’t available for the iPhone 3G.
8. You will now have the possibility to pre-install a few packages from Cydia so you don’t have to do it manually later. I will skip this part. Click the blue arrow to go to the next step.
9. You will now be in the “Custom packages settings”. Make sure Cydia is selected and you may want to select Icy as well. For what it’s worth, I do not use Icy. I only use Cydia but you’re free to select both if you want. Whatever you do, make sure at least Cydia is selected. Click the blue arrow to continue.
10. You can now set your own “Custom logos settings”. I don’t use any but again, you can choose the one pre-selected or you can even upload your own. If you choose to upload your own, remember the logo mustn’t be bigger than 320 x 480. Click the blue arrow when done to continue.
11. It is now time to start the pwnage process. You should be on the main options screen offering you 6 different options. Choose “Build” and click the blue arrow to continue.
12. You will now have to save your custom IPSW file. Save it in the “jailbreak” folder we created in step 2.
13. Your custom IPSW firmware will now be built, which may take up to 15 minutes, so be patient.
14. You will most likely be asked for your administrator password. Fill in the blanks and click OK.
15. You will then be asked if your iPhone has been pwned before. Just answer “No”.
16. Now is the most important step. You will first be asked to turn off your iPhone. Follow the instructions on your computer screen to put your iPhone into DFU mode. Basically, you have to hold the home and power buttons together for 10 seconds, then release the power button but still hold the home button. If done correctly, PwnageTool will tell you you successfully entered the DFU mode.
17. If iTunes hasn’t launched automatically, open it. iTunes should tell you it has detected an iPhone in recovery mode. Click OK.
18. In iTunes, hold the “Alt/Option” key and click Restore at the same time. DO NOT click “restore” without holding the “Alt/Option” key! A window will pop up and you’ll be able to choose the custom IPSW file you created in step12 that you saved in your “jailbreak” folder.
19. iTunes will now work on restoring your iPhone using the custom firmware.
20. Done! You will now be offered the option to set up your iPhone as a new phone or restore from a previous backup. I personally like to start fresh and I always choose to set it up as a new phone, but it’s your choice.
21. You should now see the Cydia icon on the second page of applications on your iPhone. Congratulations, you just jailbreaked your iPhone 3G 3.1 with PwnageTool.
If you have any question or concern, please leave a comment.
Saurik, the creator of Cydia, has come up with a way to downgrade the iPhone 3GS from firmware 3.1 to firmware 3.0. The method is not for the faint of heart but it can be a life saver if you accidentally upgraded your iPhone 3GS to 3.1. Saurik did a great job at explaining how and why this downgrade works and I invite you to read his article for detailed information. On my part, I will only give you a step by step on how to downgrade from 3.1 to 3.0.
1. First and foremost, you must have saved your ECID file through Cydia. If this was done, you should see the following message at the top of Cydia’s homepage: This iPhone 3G[S] has an ECID SHSH on file.
2. Now we’re going to duplicate the functionality exposed by Apple’s signature server and trick iTunes into thinking it is connected to Apple’s servers. Make sure you have iTunes 9 installed on your computer.
On a Mac, go to /etc/hosts. On a PC, go to C:\Windows\System32\drivers\etc\hosts. Open the file in a text editor and add the following entry at the bottom of the file: 74.208.105.171 gs.apple.com
Save the file and close it.
3. Now we have to put your iPhone into DFU mode. To do this, open iTunes, plug your iPhone and hold down the power and home buttons for 10 seconds, then let go of the power button but continue to hold the home button until iTunes recognizes the device with the message: “iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.” Your iPhone screen should be completely black. If you see an image on your screen, you most likely didn’t perform the previous step correctly. Try again.
4. You can now do a “normal” restore to the 3.0 software. To do this, hold down the Option key (on Mac OS X) or the SHIFT key (Windows) while clicking the Restore button in iTunes. Select the firmware 3.0 (which can be downloaded here).
Theoretically, you should be done with the downgrade. That’s just for the theory though… You’re most likely going to get several errors.
If you get the “unknown error (3002)”, it’s because you probably don’t have your ECID SHSH’s for 3.0 on file with Cydia and it is unfortunately impossible to register your device with Cydia anymore. There is no solution, your iPhone can’t be downgraded from 3.1 to 3.0 and you’re gonna have to wait for a new jailbreak.
If you get the “The iPhone “iPhone” could not be restored. An unknown error occured (1015)” error, then re-do the process all over again. You will get the same error again and it is normal. Ignore the error and jailbreak your iPhone using RedSn0w.
I agree that this is definitely not the easiest way to downgrade your iPhone from firmware 3.1 to firmware 3.0, but you don’t have much choice at this point. If you don’t feel like taking on this project, I suggest you just wait for a proper 3.1 jailbreak, which may take days, weeks, or months. I am very confident that the jailbreak community is getting closer to a 3.1 jailbreak though.
If you have any tips and tricks to make this whole process smoother, or if you have any question, please leave a comment.
The Dev Team just released PwnageTool 3.1 for Mac OS X which will let iPhone 2G/3G and iPod Touch 1G users jailbreak their device. So far, only PwnageTool is available and is for Mac only, but the Dev Team is working on updating RedSn0w for both Mac and PC.
There is still now way to jailbreak the iPhone 3GS and the iPod Touch 2G and 3G but I assume these will come in the near future.
1. GOLDEN RULE: If you are using a 3G iPhone with ultrasn0w and rely on ultrasn0w to obtain cellular service, then you should only upgrade to 3.1 with a PwnageTool created .ipsw. – Stay away from Apple’s direct updates as described here and here please get up to speed on the whole subject by reading the information contained in these posts.
2. If you have an original iPhone (1st generation) then 3.1 unlock works with this PwnageTool release. iPhone 3G users upgrading to 3.1 will need to continue using ultrasn0w with a PwnageTool created 3.1 .ipsw
3. Please read all parts of this post before downloading and using these tools.
4. Read items 1, 2 and 3 again and again.
5. At the bottom of this post are the bittorrent files for the 3.1 capable version of PwnageTool.
6. This app is suitable for the recent 3.1 release.
7. This version of PwnageTool will NOT work for the iPhone 3GS.
8. PwnageTool WILL work for Original iPhone (1st Generation), Original iPod touch (1st Generation) and the iPhone 3G.
AT&T is the most hated cell phone carrier on the planet earth, or so it seems everywhere you look. With the new iPhone OS 3.0 Apple announced iPhone MMS and tethering compatibility.
Everybody was excited until AT&T said that they will not offer this services until “later this summer” . Boo-hoo. So, people were mad, but finally got used to the fact that they have to wait for the official release of this services. Got used to it, until they start to wonder when the hell will this happen, what exactly does “later this summer” means.
The information i just got from my AT&T ninja , seems to be the same as “later this summer” . He told me that AT&T will enable MMS for its users once the new iPhone firmware 3.1 will be released . Released date for the new firmware is not certain, all we know is that it will be released towards the end of August or early September.
