I have a 2 year old Cingular voiceplan with no data plan attached other than text messaging. I put my old sim card in the iPhone (used iPhone) and when I tried to activate my iphone in iTunes, it wanted me to extend my contract by another 2 years and add $20 for the basic data plan! All I want is to use my iPhone as a PHONE with an ipod built in, and browse the web whenever near a WiFi spot. I don't want to use their 3G data "lines" or whatever. How can I get around this? Unlock my phone or something?
