No SIM card installed error..but another iPhone SIM works?
A problem arose yesterday that I have never run into before when I jailbroke a friend's 2G iPhone. Said iPhone's original firmware before Pwnage was 2.2.1. I used the PwnageTool 2.2.5 to unlock and jailbreak using default settings on everything but the logos. Process goes smoothly as usual. After everything finishes, I pop in my SIM from my iPhone that is still in jail - works fine. I pop in friend's card and get the "No SIM card installed" error. The strange thing is that my SIM works, but friend's doesn't. A possibility that I have is that the SIM is damaged, as it does have some pretty serious indentations on the contact areas. Also, the "Import SIM contacts" setting does not exist when the SIM is in the tray, although I know there are SIM contacts present. Anyone have any ideas?
Iphone no sim card installed
The same thing... Before two weeks iphone 2g displayed NO SIM CARD INSTALLED after one year of normal usage. I try everything and it cant be fixed. hardware problem on logic board... the costs of repairing is too big.
Same thing here. Can't be hardware
My phone suddenly started to show a "no sim" and "invalid sim" error. Tried everything.
Then I bought another 2g phone from a friend and after I unlocked it with redsnow, same problem. The sim works on a regular cell phone, but not in either iPhone 2g.
Something is screwy with iPhone software.
