At a press conference in China, Sony Ericsson unintentionally showed slides of as-yet-unreleased and unannounced handsets, including the T707, codenamed Elle, as well as the M610. The pages reveal the T707 is a quad-band GSM and dual-band UMTS/HSPA handset and is due to sport a 2.2-inch display. Storage will come from a 1GB Memory Stick Micro card, while the operating system will be OSE from Enea. There is still no word of when the T707 will launch, although it is expected to be fairly soon and in at least five colors.

The mistake in the presentation also involved other handsets, including the Walkman P3, which has been discontinued. The photo also did not match up with the handset's description. Another older handset in the slides, the M610, dates back to 2007. [via NewLaunches]
