[1.1.4] [Advice] No GSM signal, tried all methods
I just got an iPhone from a friend that lives in the US. He's been using it for some time and has had no problems with it. Thing is he gave it to me and now i cant reach him by telephone/mail.
My problem is as follows:
I cant get the gsm signal. I've tried all methods. Virginizing from 1.1.1 and from 1.0.2. I've tried just plain unlocking it with ZiPhone/PwnageTool/iLiberty+/NorPlus.
Since i cant get ahold of my friend i dont know what OTB firmwire the phone had.
However when i unlocked it with NorPlus (kinda like pwnage tool but with Norwegian stuff preadded) i got a GSM signal for 5 minutes and I was able to receive sms and call, but after 2-3 minutes i just lost signal and haven't been able to get it to work since then.
Another problem i might have had is when unlocking it for virginizing, the problem here was that i couldn't get the jailbreakme.com unlocker to work so i had to use a different unlocker.
Does anyone have any clue what my problem is? I'm starting to think it might just be the my Sim-card inside the phone isn't sitting well enough, however i doubt this because I even tried taping the Sim to the metal attachment thing, and still didn't get it to work.
Any ideas/advice is welcome, I'm really desperate.
Note: everything else in the iPhone works like a charm.
