I can't believe I did it. My 3G running 3.0.1 was running fine. I decided to try the MMS enable from sinfuliphone repo and After the instal it wants to reboot for changes to take place and my 3G stops at the apple logo. Idiot needs help. WHat should I do where to start. Need Help.
After reading sinfuliphones page on MMS and tethering I see that I should've installed the MMS and Tethering hack and no the one names MMS 2G on firmware 3.0....
What should I do. Is there a way for itunes to update to 3.1.2 instead of 3.1.3?
I see a guide on updating with redsn0w 9.4 but it seems to show the steps using a 2G phone updating to 3.1.3 and with some loophole going back to 3.1.2

What will a restore do in iTunes? I don't remember backing up for a loong time.
