Right now i'm on a family plan with 2 other phones. Can i just purchase an iphone and keep the exact same plan i have now? I don't want to get a data plan right away, i want to see how much i would actually use the internet and go from there. To clarify, can i keep my non-smart phone plan (voice and 200 txts/month) and have that apply to the 3g iphone or do i need to sign up for some other sort of plan? If that is the case i will not be getting it. QUICK RESPONSES ARE APPRECIATED!
