I love the iphone, but not much into making calls. I'm sick of paying $70 per month. My 2yr agreement is up june 29th and I'm going to cancel. My question is will i still be able to use the phone as if it were an ipod touch? I still would like to use it for the music, videos and wifi. If not, will the phone be worthless? What can I get for a used original iphone? Anyone else going to cancel after their 2yr deal?
