iPhone keeps crashing (iOS6, BB 05.13.04, unlocked with Ultrasn0w)

Hi!

I've got an iPhone 3GS, new bootrom, running iOS 6. It is jailbroken with redsn0w, has the 05.13.04 baseband and is unlocked with Ultrasn0w & Ultrasn0w fixer for iOS 6! When it had iOS 5 running on it i upgraded the baseband to 06.15.00 to unlock it. It had some crashes, but really rare. Now, after downgrading the baseband to 05.13.04 and updating to iOS 6, it keeps crashing while making phonecalls or using apps longer than a few minutes. Now, since it has the new bootrom, it has a tethered jailbreak, so i'm screwed if i'm not at home when it crashes once again.

Does anyone know this kind of problem ?? I'm kinda freaking out here !!

Greetings,

Caspar

Is the main reason of you to jailbreak is to unlock your phone so you can use with other networks? If it is then there are services on ebay that provide unlocking for 14 pounds. I am in the UK. Write back with comments.

John: Yes, unfortunately it is! The phone is locked on orange Austria and i'm using it with 3 AT. So, do you think it's possible to unlock an austrian device with a british unlockservice??

Dakenson: Ultrasn0w and Ultrasn0w fixer is everything I installed. Yeah I use the just boot many times a day! ;-) Anyway, thanks, I hope I'll find a way to factory unlock it.

If you installed apps or tweaks from Cydia it's probable that one of them is causing the issue (like Activator) as it has not been tested and edited to support iOS 6.

Also, the iOS 6 jailbrek is tethered, so you must connect your iPhone to redsn0w and click on extras>just boot in order for it to boot properly, you must do this every time you want to turn off or reboot your device.

hi,

as it is a iphone 3gs and i think its older than 2 years, i would suggest to go to an orange shop and let it officially unlock there. it costs 50 euros.
