Not everyone is exactly in the market for a blinging Walkman phone, and the suits at Sony Ericsson must be pretty aware of that. That doesn’t mean, however, that the company is ignoring the entry-level end of the market, because just yesterday, Sony Ericsson unveiled three new additions to their family: the Z530, K510, and K310.

All three handsets are tri-band GSM and come with not-huge 128×160 LCD screens. The Z530 is your standard SE clamshell, and is the baby brother to the W300i Walkman phone. It only comes with a VGA shooter, but you’ll be able to cram in more storage space via the M2 slot.

The VGA cam-equipped K310 seems to be as basic as it comes, because although it plays music, there’s only 15MB on board, whereas the K510 bumps that number just a touch to 28MB. On the plus side, the K510 looks sleeker and comes with a 1.3 megapixel digital camera.

Stay tuned, and keep your eyes and ears peeled for more information from Sony Ericsson regarding price and availability, because it seems they’re reserving that news for another day.
