If you are under 18, you wont be able to sign a contract anyways. YOu would have to have someone over 18 (parent, ect) take on that risk. Personally, you would be better off with prepaid. Tmobile seems to have the best prepaid deals around. I remember just a few weeks ago, Target had a Tmobile phone plus a $100 airtime card for $88. After you add $100 to your phone, your airtime lasts for a year (unless you use it all). Plus, if you want, they sell a prepaid sidekick, and you can have unlimited internet/chat for $1/day. Id check out howardforums.com. they have areas for most of the major prepaid and MVNO providers (services that use other companies networks like Virgin, Boost, Amped, ect). Do some research and find out what works for you.
