I just confirmed with ATT that I am eligible for a full discount on 6/28/10. I bought my 3GS on launch day. My monthly plan is $114 plus tax/fees.
I was threatening to cancel and asked to find out my contract dates for 5 phones I have with them (4 are on a different account) and complained about the two data plans and that there is no tethering available, etc. The person I was speaking with said that she believes tethering will be offered in June. I would take this with a grain of salt as she may have been telling me what I wanted to hear but that is what she said to me. I also learned that by 8/10, it would cost me $250 to get all 5 lines off contract which has me considering other carriers, in particular, Verizon. I am a huge Apple fan but I will take a look at the HTC Incredible phone. I do not know much about them as I never cared but I have a good friend who is a phone nut, that speaks highly of the phone.
