I suppose this should be in a WIKI or something, but I can't find it.

I have a Treo 700Wx from Sprint, and I want to use it on Verizon (Actually PagePlus, Verizon reseller). I have flashed a WM6.1 ROM, and when I turn the phone on it says "Welcome to Verizon", but the status line at the top of the screen still says "Sprint", and the Verizon provisioning codes (*22890 0r *22800) do not work.

I'm familiar with unlocking GSM phones, but I can't find any information on how to do this with the Treo.

Can anyone help?
