iPhone 3GS problems | Phone/Device Issues and Features | Consumer forum

my iphone resets (re-starts, reboots call it what you will) about three minutes after my SIM is inserted. This problem started about 2 months after I got my first SpeakOut SIM which worked fine (until 2 months later). I tried registering a new SIM with my iphone and when I registered the second time I wasn't given a phone number, I inserted the SIM and my phone rebooted as it did before.

please help, I'm a teenager and can't survive without my iPhone
