Successful unlock

I have successfully unlocked my HP iPaq 6315 PocketPC phone. Now I just need a "foreign" SIM card to test it out. A word of advice for others before attempting to unlock T-Mobile's phones: make sure the unlock code is for your phone's EMEI number. You can get the phone's EMEI number by dialing *#06#. My reason for caution? The first set of unlock codes sent by T-Mobile were for the wrong EMEI numbers. It wasn't after two failed attempts on my HP 6315 did I find the problem.
