I currently have a BlackBerry Curve, used to have an LG F9100 ... the Curve has too many bells and whistles for me and the keyboard is too small for my pudgy fingers when trying to type.
The F9100 has a good keyboard but the screen is so effin small it's not much good for anything other than plain texting.
There's scads of new & used F9100's on eBay, some of them with B.I.N. prices exceeding 200 bux ... be careful!!!! I bought mine in an eBay auction for 65 bux last year, new in box, so it is definitely not a multi-hundred dollar phone. You might also consider the LG F9200 which is basically just a cosmetically enhanced F9100.
I would like something like the LG Voyager or enV (both Verizon phones) or even a SideKick, but the only wide-qwerty phones in the ATT stable currently is the Pantech Duo, which is cool but too small for my fingers, and the HTC (aka ATT) Tilt, which is bigger but still way too expensive (300 bux with a contract!).
Anybody know of a website where one could simply look up models of phones to see if they're unlockable and if so, what services they'd work on? I've been burned before when buying unlocked GSM cell phones on eBay that the seller said would work on Cingular, but didn't. It's hard to tell who to trust ... there are LG Voyagers on eBay indicating they're GSM which would make them potentially compatible with ATT, but the LG website itself shows the Voyager as CDMA only.
