Actually i have att phone. I have 4 phones on my lines, and internet i have disabled internet on it. Now my friend gave me his Att nokia e71 and he unlocked it. If i put my sim in that phone would i be charged for the $30 data plan. Cause i heard sum-where that att track some imei no, and activates the plan. So im worries if i would be charged or not, i dont want to pay for the data plan. My friends phone is att e71x, he gave it to me and moreover i was thinking of buying a new unlocked pone from dell.com. Im intersted in buying nokia n97, or N900 or N97 mini. Would i be charged for the data plans on these unlocked phones.. PLz help guyzz..
