they're not going to believe it until they try it, but as for me all I can say is thank you bcuz it worked for me. And by installing Corona 1.0.5 and rebooted the device, it fix the problem I had with the the device getting stuck on apple logo after rebooting. THANKS MAN!!

my 3gs is not a factory unlock iphone, I bricked my previuos 3gs by flashing the ipad bb, so I went to the apple store to replace it and they replaced the iphone (believe it or not) so I can assure you is not factory unlock.
you said your phone stuck on apple logo after rebooting?
