Review: Sony Ericsson C905a
The C905a has a healthy number of preloaded applications and it is easy to search through AT&T's portal to find applications, games and other content. It's no "Apps Store" mind you, but if you're looking for simple things to personalize your phone, this is where you get it.
The C905a has Bluetooth 2.0+EDR and a huge number of supported profiles. Using both regular and stereo headsets was a snap. The phone paired with headsets easily enough, and calls sounded decent. I wasn't thrilled with the quality of music through stereo Bluetooth headset, though. I was able to push files back and forth, send contact information, beam photos, etc.
If you want to check the time on your phone, just hit the volume toggle on the right side of the C905a. Doing so will turn on the front display, which shows you your signal level, the time and your battery status. The display is small, but it is still easy enough to read the time, even at an arm's length when outdoors.
The C905a is pre-loaded with AT&T's GPS service. It worked OK. In the time I spent with it, it was only able to get my approximate location (within a 100 yards or so); it never pinpointed me directly. Same for Google Maps. It can be hard to trust a map when you know the GPS is several hundred feet off.
