Hi there, I'm a newbie in LYN... My iPhone keeps restarting when it received carrier signal. But when I put the phone in airplane mode or i take out the SIM card, it works fine. Sometimes after restart, it will display battery low warning. When the battery is low, even I put it plugged and try to connect to carrier, the problem will occur again. The only possible time to connect to carrier is when battery is full + charger plugged in. The problem occurs since OS2.2.1.. But when i first got the phone, it has no problem. Now I've changed my battery (chapalang battery RM40+) and upgraded my OS to FW3.0 .May I know what is wrong with my iPhone? Any sifus out there? TQ

my iPhone spec:

iPhone 2G 8GB
OS3.0 (7A341) Jailbroken

I've tried other SIM cards, still the same... T.T.... 3.2.1 can be jailbroken? Because I'm using unlocked set... xD

ok tq bro!!... but any other sifus know bout my problem now? I'm actually suspecting either OS or GSM Module...
