i'm tired of my father complain about the high cell phone bill so i plan to sign a 2 year contract. i want to get an iphone 4 but i am not due for an upgrade until october of this year. right now under my father's plan, i have 5000 texts a month which i've been going over recently. i've never had internet on my phone. so if i get my own plan, i'd like to have unlimited (or more than 5000) texting and unlimited web. i don't talk on the phone too much, but as long as i can have free calls to my parents, i should be fine. about how much would this cost me?
