I have an illegally unlocked & Jailbroken AT&T iPhone 4 16GB, using limera1n & Ultrasn0w on Cydia.
The unlock & Jailbreak was done without a Gevey SIM.
I have iOS 4.0.2 (8A400) installed with Modem Firmware 01.59.00. Model MC608LL.
I have always had some Network Problems on start up, after Shut Down & Re-boot the GSM Network is not detected immediately & i have to restart a couple of times.
Ultasn0w has not been removed after the jailbreak.
The other problem i face is that 3G & iPhone Data Plans don't work.WiFi is fine.
Is it possible to upgrade to iOS 5.1.1 without upgrading the base band ?
Will the new jailbreak be stable or should i wait for some time ?
