Dear Nokia2003

Have u received my PM?? just wonder why my sent folder still empty after 2 times I send pm to you.
Anyway, I got this trick from mypdacafe.com forum so the credit should goes to them.
Okay, 1st step put atnt sim card or any working simcard, digi, maxis (other than celcom) n power on.. Wait till got some signal bar / no network display..

2. Go to setting, carrier. It will search for network. (if no carier show, go back home and wait a while). wait till all 3 network found. (leave the right tick to default "automatic")

3. Press power button (put iphone on standy NOT OFF).

4. Replace the simcard with celcom. (the msg no sim will pop up.. just ignore it and just press the power button to put it on standby mode again)

5. Press power button then 'slide to unlock' You will see the network list. Choose celcom and go home.. Never enter carrier menu again.

Note: on step 5 you need to unlock (keying sim card pin) 1st if you enable the sim lock.

Good Luck
