I own this phone....I have had it for over a week now. I was due an up-grade, and then AT&T matched the lower price that was being offered by Walmart mobile. I also received trade-in cash for my older Samsung galaxy 2...so, it dropped the price and made it reasonable. I can answer any questions you might have...I have learned a lot in this past week! I can say that I am really liking the phone thus far...my first experience with a windows phone, but I am impressed!
I've got an LG flip phone that I got when AT&T was still Cingular. Maybe it has collector value by now... ;-)
I do too.
Also have the original Sidekick from Tmobile. Lol
ETA: I also have a phone from Cricket when they first introduced their $19.99 monthly plan. Those were the days. Now with Sprint and they're taking us for every nickle and dime we have!!! Lol
