Step 1: Get MetroPCS to add your phone's ESN/MEID to their database. I think non-corporate authorized MetroPCS dealerships can do this, but I'm not certain. If you can't do this step, then there's no point in going any further. Get your MDN and MIN numbers from them. Also be sure to ask them what your region's SID/NID pair should be. A service technician should know the answer to this. Record your SID/NID pair.

Step 2: Download a MetroPCS PRL and copy it onto your memory card:

Step 3: Search the PPCGeeks FTP site for the GetSPC utility. Copy it to your memory card and run it from there. Be sure to use ALL CAPITAL LETTERS when inputting your phone's ESN number. Record your device's SPC code.

Step 4: Run the EPST utility by pressing ##778 # OR Talk (depending on your carrier/ROM). Choose Edit and enter the SPC you recorded from earlier. Provision your phone manually by entering your MetroPCS MDN/MIN pair and your carrier's SID/NID pair. Load the PRL that you have on the memory card. Enter all of MetroPCS's WAP information (search the web for it) including the Security user name and password. Press OK to reboot the phone.

Done.

You can attempt to provision the phone over-the-air via *228, but it might not work. With some carriers, your SPC must be all zeros for *228 to work.

You will still need to set-up MetroPCS WAP in the connection settings, as well as the MMS settings in ArcSoft, along with any registry changes necessary. There should be dozens of threads here or over at Howard Forums or XDA Developers on how to do this.

Cheers!
