The mysterious Sony Ericsson slider we saw last month has been officially announced as the T303.  Triband GSM (900/1800/1900 or 850/1800/1900), the cellphone is aimed very much at the entry-level market; available in black or silver, it has a metal and chrome finish and mirror-effect screen, measures 83 x 47 x 14.7 mm and weighs 93 grams.  Bluetooth is present – in case you want to offload photos from the 1.3-megapixel camera – as is an FM radio and Sony Ericsson’s TrackID music identification app.

Otherwise it’s all very simplistic: a 1.8-inch 128 x 160 display, 8MB of internal memory with no way to expand storage, a basic collection of organiser apps, support for MP3 ringtones and a WAP 2.0 internet browser.  Sony Ericsson are promising up to 9hrs talktime or 400hrs standby.

It’ll launch mid-2008 in “selected markets”.  No price has been suggested.
