LG last night introduced the CU515, a sleek HSDPA flip phone for AT&T. The CU515 is an update in design to the CU500v though it maintains the same feature set. The CU515 is a quad-band GSM phone with 850/1900 HSDPA. It has shiny, slim form with a small monochrome external display a large color screen on the inside. It has stereo Bluetooth, a 1.3 Megapixel camera for pictures and video sharing, and a microSD slot. LG did not reveal when it will go on sale, but it will be most likely be available from AT&T soon.
