Of course nothing complements a bevy of handset announcements like a similarly sized list of accessories, and Sony Ericsson has done itself proud today in that regard. Headsets — both Bluetooth and wired — were the order of the day with a smattering of GPS, desk stand, and FM transmitter thrown in for good measure. The HBH-DS200 is a pretty standard Bluetooth headset fare with shirt clip, a 3.5 mm jack to let you swap in your own cans (fantastic feature if you have a nice set at home) and up to 7 hours listening time; it’ll ship in box with the W960.

In case you hadnt noticed, Virgin Mobile rocks an ever-so-slightly higher end lineup north of the border than it does in the US, and to that end, it’s just released the RAZR 2 V9m. We all know the drill here by now: 2 inch external QVGA display with music controls, 2.2 inch internal QVGA display, stereo Bluetooth, EV-DO, microSD expansion, and a 2 megapixel camera, all of which are ready to sit just above the KRZR in Virgin’s stable. Grab it now for $149 CAD (about $147) on a three-year deal.

Prevent the Memory Effect - Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries, which do not suffer from the memory effect. Do not leave the battery dormant for long periods of time.
Always use a battery charger, which is by the same manufacturer as your phone, it gives it more life. It also helps if you overcharge your battery now and then.
