They sell unlock codes on ebay for this phone. I just didn't know if you could use the pay as you go plan with a windows 7 phone.
Wasn't sure if there was some kind of tmobile restriction on that or if they would make you get a more expensive plan for data. I'll probably try it and see if it will work. I think it will only cost me like $15.00-$20.00 to see if it will work.
