hi,

i have a stock iPhone 3g. say i jailbreak it and something goes horribly wrong. is it possible to restore it back to its original stock state and have it work again?

thank you

As long as you follow the instructions and jailbreak it RIGHT....then yes.

I got bored, jailbroke mine and then restored back to normal. No problems.

may i ask....

how come you restored it back after you jailbroke it?
