Ok so my school has this shitty rule that if you have your phone on you they take it away for 30 days. Well that happened to me the other day and I cant go 30 days without a phone. I heard that people use their old phones or other peoples old phones and reactivate them. I want to do this but i want to know if it will cost money since my contract isnt up yet. Like i have (had) the blackberry bold and if i use someones old Iphone, does it charge me money?
