I have an iPhone 2G that will not start.

I turned it off while it was plugged into my charger and everything seemed ok, until I relized that it would not turn back on again.

I cannot use the home/sleep button because it does not work.
And whenever I plug it into a wall charger or a computer charger, it still won't turn on.

Also, I can't take it to an Apple store because it is unlocked and jailbroken.

Any suggestions?
