Review: Sony Ericsson W580i
Text and MMS, email and even RSS each have their own inbox in Sony Ericsson's messaging application. Setup is relatively painless for each of these. The display of each type of message is different, but all are clear and easy to read. However for some reason all SMS are displayed with "Text:" preceding the message. This is redundant (of course it's text) and annoying.
Composing messages starts with a full screen window to compose your message. Once you are done, the address screen lists recent contacts you've sent texts to in addition to links to your contact list or number entry.
