i've a question: i followed the guide (http://www.hackint0sh.org/forum/showthread.php?t=11966) and now the iphone works great. (firmware 1.0.2 ad baseband 04.01.13_G)
But if i want to make a restore to firmware 1.1.1 is that possible?
does the restore modify the baseband?
What about an upgrade?
And if make the restore do i have to use anysim again?
