I've just upgraded my iphone from v2.0 to v2.1 using pwnage..
after that everything was working well but the only weird thing is I cant make outgoing calls, it always show "call failed".
It is still working under Maxis network and can receive incoming call and SMS, I can send SMS too.
Its not my credit problem becos Im using postpaid and I've tried my sim card on other phone, I was able to make outgoing call.

I thought the unlocking process is not well done..
I decided to restore the iphone to v2.1 via iTunes, this time I use QuickPwn to unlock and jailbreak..
After jb and unlock using QuickPwn, the problem still exist.. I have tried to put in a working Digi sim card.. the same problem stil exist.

Hopefully someone can get my problem resolved here.
Thanks for sharing and helping
