    Sorry you can't use your 8830 on tmobile,sprint uses cdma network(no simcard),tmobile uses gsm network(simcard)and the two networks are imcompatible,if you want tmobile you will have to sign up,but then you'll be able to get the curve 8320,its a sweet device and you'll like it better trust me,I had a 8830,you won't be disappointed with the curve

    i got the 8830 for free and it has a sim card slot. I'm wondering if there a way to maybe reformat the phone or something to get it to use tmobile possible? and the 8830 can run on GPRS which is suppose to be another gsm?

    The 8830 has a sim card slot for use outside the US. It has GSM 900 and 1800mhz frequencies for use outside the US. In the US you need 850 and/or 1900mhz frequencies for the phone to work on T-mobile or Att. The 8830 has a CDMA for use in the US, that ties it to Verizon, Sprint and maybe Alltel. In short, cool that you got a free phone, but there is no way for it to work with T-mobile or Att. Sell it on ebay and buy an 8320 for T-mobile.
