Menyambung tulisan sebelumnya ttg jailbreak dan unlock iPhone temen, setelah stack di 05.15.04 krn Redsn0w 0.9.6beta4 tidak support utk UltraSn0w 1.2, akhirnya si dia mengijinkan dijailbreak lagi (setelah direstore) dgn Redsn0w 0.9.6beta5. Presedurnya sama. Berikut snapshootnya.

masih ada cara lain selain upgrade baseband ke 06.15.00 yaitu :
install SAM di cydia dari repo.bingner.com … jalankan SAM
masuk utilities , pilih lockdown to stock .. setelah di lock , connect to itunes … beress.. restart
here’s how to fix the WiFI problem:
1. Settings
2. General
3. Reset…
4. Reset Network Settings
This will wipe all your WiFi settings out and restart the phone. When it starts up again, you’ll have to reenter passwords for the WiFi networks you use. Ever since the reset, my phone seems to join my network normally.
Upgrading your iPhone 3GS baseband to the 06.15.00 iPad baseband hack to unlock MAY cause you to lose your GPS!
