Hello everyone- I have a Gevey Turbo Sim equipped iPhone 4 that I use with T-Mobile. The phone was previously running iOS 4.1 perfectly with the sim. However, today I decided to upgrade to iOS 5. I used Redsn0w, keeping my baseband intact on 02.10.04 Now, when I start up the phone, I get the message where it says to wait 15 seconds and dial 112, and press accept. The phone then says searching and no signal... Could anyone help me.. I have double checked the phone is still on the 02.10.04 baseband, so that's not the issue. Do I need to change any special settings for iOS 5? Thanks!
