Sony Ericsson today announced its first 3G phone for the US as well as its first slider bound for our shores. Both phones feature Bluetooth and 2 Megapixel cameras and a Memory Stick M2 slot.

• Z750: Looks like a US version of the Z610 clamshell Sony Ericsson released late last year with quad-band GSM/EDGE and tri-band HSDPA, making the Z750 a prime candidate for Cingular. Features a mirrored exterior with a monochrome screen hidden beneath. Also features a customizable RSS ticker on the home screen and Exchange synchronization.
• W580: A small, 14mm thick slider with Walkman functionality. Quad-band GSM/EDGE with a pedometer and FM Radio. (Not to be confused with the W850 Walkman slider for Europe.)
