    Hi guys, new here.

    My iPhone 3G is unlocked/jailbroken in version 3.1.2. It started acting weird yesterday and my phone keeps rebooting randomly/spontaneously. I can make calls sometimes and then the phone would crash and restart. Sometimes the phone is just sitting on my bed and it restarts by itself.

    I haven't made any changes on my phone or updated/install anything.

    What can be the problem? What can I do to diagnose/fix this?

    Thanks!

    Possibly battery issue. Have seen a few. Might be circuit board though. I would try a battery change first.
