Sony Ericsson has introduced a new entry-level handset T715 that offers 3G connectivity. The slider handset features 2.2-inch 240 x 320 LCD screen, 3.2-megapixel camera, quad band GSM, tri band UMTS, Bluetooth, A-GPS, 90MB of internal storage and microSD card slot. The phone will support Exchange Active Sync, IM, MMS, SMS and Google Maps. It measures 3.6” x 1.88” x 0.58” and weighs 3.4 ounces.

Along with T715, Sony also announced the more interesting VH310 Bluetooth headset that offers excellent 11 hours talk time and 500 hours standby. The headset ships with three different ear tip and two different ear hooks for perfect fit. The VH310 weighs just 0.35 ounces and will ship in black and silver colors.  Most of the Bluetooth headset we have seen hardly last three or four hours, a headset rated at 11 hours battery life should at least last for around 8 hours in real life, which would be excellent. Sony Ericsson hasn’t announced shipping dates or pricing for both the devices.
