Working Jailbroken Phone now unuseable....
I have a Iphone 3G phone. I used QUICKPWN (Codename "Pwnmetheus") 2.1-1 to jailbreak the phone. It worked fine for 4 weeks but now have a problem.
The phone will not pick up my o2 SIM. (Stays in Emergency Call mode) I have tried restoring it, no luck.
I placed the O2 SIM into an unlocked Nokia 6300 phone and the O2 network is picked up. So, it seems its not the SIM card, but the phone itself.
I need to take the phone back to Apple.
If I upgrade the firmware to the latest version, will the Apple Genius be able to detect I had jailbroken the phone?
What do I need to do to make sure the genius is NOT able to detect it was jailbroken???
Thanks in advance for your help!
