Sony Ericsson hits up the higher end with four new phones

Nokia had their day in the sun earlier this week, and now it’s someone else’s turn. Sony Ericsson is release happy today, with no fewer than four new mid- to high-end handsets: Z558, Z550a, W958, and W830.

The Z558 and Z550a clamshells are functionally and aesthetically identical, except that the latter is quad-band GSM with 25MB of internal memory. They share Memory Stick Micro expansion, push email, a 1.3 megapixel camera, and handwriting recognition.

The W958 Walkman phone stashes 4GB of content, be it music (MP3, AAC, W4A, etc), 30fps video, or whatever else tickles your fancy. You’ll also find Opera 8.0, Bluetooth 1.2, and handwriting recognition (but no memory expansion).

Last but not least is the W830 with its 2 megapixel camera, video recording, Macromedia Flash, and a bundled 1GB Memory Stick Pro Duo.
