Three relatively entry-level phones were announced today by Sony Ericsson, the K510, K310 and Z530. The K phones are in the candybar form-factor, and the Z phone is in the clamshell form-factor.
First, the K510, which has a 1.3-megapixel camera, tri-band GSM, 4x digital zoom, 28 MB internal memory, and an optional "true" camera flash with the MXE-60. There's also an external antenna connector, Bluetooth, and is available in Midnight Black or Polished Purple.
The K310 is a lower-end phone with only a VGA camera, MP3 support, 4x digital zoom, and 15 MB internal memory. Not much else of note here.
Lastly the Z530 is the only one of these three with expandable Memory Stick Micro slot that can hold a 1GB stick. It also has a 4x digital zoom on its VGA camera, Bluetooth, USB 2.0 connectivity, and a full HTML browser.
