The Sony Ericsson T715 is a quad-band GSM with European 3G support. It is scheduled for Q3 2009 launch in select markets. Fortunately, there will also be an American version, the T715a, which is expected to sport tri-band 3G connectivity (850/1900/2100). Finally, pricing information is currently unavailable.
In addition, the manufacturer has announced a new Bluetooth handsfree, named the VH310. It weighs about 0.35 oz (10 grams) and should allow more than 20 days of standby on one charge. However, the VH310 is just an optional accessory to the T715 and will not come bundled with the phone.
