Sony Ericsson has been extremely successful with the W880i, so much so that they have made minor improvements and now they are going to release the W890i. I still have my W880i and I do enjoy a phone for once that doesn’t have issues after three months. Its as thing as a CD case, and has 26 MB internal memory not including the expansion memory which could be added depending on the memory that you buy for it.
There has been a slight improvement on the network capabilities, so it handle all these GSM/DATA networks EDGE, GSM 850/900/1800/1900 MHz, HSDPA and UMTS 2100 MHz networks. It coms in brown and silver, very thin, and the TrackID software which makes it successful a good mp3 playing phone. And improved camera from 2 MP to 3 MP, so that is a good thing for sure.
