After you have jailbroken the iPhone firmware 3.1, you will discover there is no carrier logo (pictured above on the left). In the settings, it can’t display the carrier you are using. But, the phone functions actually still work. You can still call your friends and get online. Hence, it would be only a cosmetic issue.

If you feel uncomfortable and just want the carrier logo, you can try to install the MakeItMine freeware from Cydia. Type the name of the carrier you are using, and click “Carrier” at the top left. Quit the app and you will have the carrier text.(pictured above on the right) I know it does not really solve the problem, and the text won’t change after you switch the SIM card, but it actually looks better than nothing. Right?

DETAILS:

1. GOLDEN RULE: If you are using a iPhone 3G or iPhone 3G(S) with ultrasn0w and rely on ultrasn0w to obtain cellular service then you should only update your device with an .ipsw that is made with the new PwnageTool. There are no second chances with this. You need to remember that PwnageTool will provide an upgrade path to newer versions of the iPhone software in the future.
2. Please read all parts of this post before downloading and using these tools.
3. Read items 1, 2 and 3 again and again.
4. At the bottom of this post are the bittorrent files for the 3.1 capable version of PwnageTool.
5. PwnageTool will work for the iPhone 3GS assuming you have already Pwned it at 3.0 or 3.0.1
6. PwnageTool will work for the iPod touch 2G assuming you have already Pwned it at 3.0 or 3.0.1
7. PwnageTool WILL work for Original iPhone (1st Generation), the iPhone 3G and iPhone 3G(S) and the iPod touch (1st Generation and 2nd Generation) but NOT the iPod touch 3rd generation.
8. For 3G and 3G(S) users who are Pwned, PwnageTool is your key to updating in the future, just remember to never install an update directly from Apple, always use an .ipsw that has been created with PwnageTool.
9. There is no Windows version of PwnageTool it is a Mac OS X tool only, we are not developing a Windows version of PwnageTool.

But don’t worry…our PwnageTool program — when it’s updated for 3.1 — will let you update your main firmware without touching your baseband firmware, so you can still have the best of both worlds.  But you must be diligent about saying “no” to your iTunes request this week to update your firmware.
