you should get a standard non-pda device and stick your sim in and use it for a while then call in and fix the data plan. then after you can confirm that you have it, put it back in y,the device you ant. the downside is that if yhou still try to use a tmo branded device rather then an unbranded device, thier system can auto detect it being a high data use device and make it so that every time you try to use the internet opuitside the tzones, it will give you an error to pay an addition 1.99 per mb. you can use internet2.voicestream.com or epc.tmobile.com i have found recently that i had to change the apn back and forth as i started getting errors. but......still working!
