the other thing to consider, is most of these new phones may not be released until early 2012. there will be a few more phones coming out this fall for the holidays, but nothing worth waiting for IMO. the early 2012 phones are the ones we will want. in addition with some of this new hardware, like gyroscopes and dual core porcessors, apps and games wont really utilize them until next year...
i agree with finding one on ebay or amazon preowned, and saving the upgrade. wish i would have done that, but i got a free hd7 so it was really hard to resist and i love the phone!!! although it only has a 1230 mah battery, it lasts me almost a whole day with moderate use...
