If you're eligible for upgrade, it's $200.
I'll be eligible on 11/1. Hopefully, all the rush will be over with by then!
However, I'm still debating if I should stay with Android or move over to iPhone. My HTC Evo works perfect even after almost 2 yrs. I have no complain about it. Actually, this is the first phone I've really LOVED other than StarTec (remember those? I used make and repair them!)! And I've been dealing with cell phones since '89! Back when they used to be called brick phones! LOL
