...card in a blackberry for 2minutes? my friends got an old at&t phone, it was a blackberry and she has verizon(they dont have sim cards), so i said lets try putting my sim card in to see if it works and stuff. so i put it in for literally 2 minutes. and after i get home from school, i got a text message from at&t that says "did you know that you need a data plan for a smartphone? we have added an appropiate data plan." is this a advertisement or is for real???????????? cuz when i check online, i still have the five dollars plan i always have!
