I have with me old T-mobile G1 android phone and my question is can I use android phone with my Straight Talk Phone? I know it illegal but I paid a lot of money for it when it first came out and I can still use the internet through it, all I would like it to do now is make phone calls, but through my Straight Talk service. I know it is somehow possible because my phone is also jail broken. So can it be possible. Please help.
