Ok, maybe I dont know what I am doing, this nokia was a tmobile phone, I unlocked to use as a cingular. I want to now use it again as a tmobile. I put my tmobile sim into the phone and it works, is that normal? OMG, help! I dont want the use of the tmobile card in this phone to be charged to my cingular account, cingular is home and tmobile is work, tmobile flip phone broke and this nokia 6010 lays around as an extra. Please tell me what is going on??
