Of course there is more than just photography to this handset. Music playing is another stalwart of Sony Ericsson mobiles and the player here offers good playback features despite this not being a Walkman branded phone. There is 160MB of built in memory and a Memory Stick Micro card slot under the battery cover which you can get to without removing the battery itself.
I am coming to loathe Sony Ericsson's chunky earpiece connector that generally doubles for mains power and PC connection. It is simply too plasticky, too large and too ugly for the latest crop of mobiles.
Nowhere is that more apparent than with the C902. The mains power connector has a through port so you can charge the phone and use a headset at the same time, but the side-mounted socket either used singly for the headset or along with the mains power charger is ugly, ugly, ugly.
On the plus side Sony Ericsson provides a 3.5mm connector beyond the mic of its bundled headset so you can use your own earphones, and battery life is amazingly good. I got 15 hours 38 minutes of non-stop music from a full battery charge.
Among the other features to be found here is a very good web browser, RSS feed reader, FM radio, two-way video calling, Bluetooth (and output to a Bluetooth stereo headset), mobile email and IM, a sound recorder, calculator, task manger five alarms, calendar, notes taker, stopwatch and timer.
It is a shame that Sony Ericsson doesn't feel the need to include Wi-Fi in a phone as capable as this one is. It isn't often I hanker for operator free Internet capability from a Sony Ericsson handset, but this one is an exception.
The good camera and excellent hardware design help the C902 stand out. The horrid peripheral jack really has had its day, and I'd like Wi-Fi, but even with those gripes this is a superb mobile phone.
