As a Sony fan, I expected this phone to be good but it has surpassed all expectations.
I also own the W200i which is good but I've found myself using the camera more than I ever anticipated so it was time for an upgrade - and I haven't been disappointed. The camera is very good with far more features than I anticipated including auto focus, white balance, a panorama mode (even my still cameras don't offer this!), scene modes (eg landscape, beach/snow, twilight..), 4 photo resolutions, effects (eg sepia), spot metering, and a light with most of these also available in the video mode together with the ability to pause and resume filming a video. Post-production, the phone also offers a basic editing facility via Photo DJ whereby exposure can be corrected and red-eye removed.
The music player is similarly impressive with track recognition, good sound quality, a spatial stereo effect and equaliser - and yes, I really am describing a phone and not an MP3 player! Mobile TV is available and videos can be downloaded for playback. Naturally, there is a radio too and reception, using the antennae incorporated into the headset, is very good.
The phone will support up to 2GB M2 memory stick which will hold a large number of music tracks, photos and videos and a 256mb M2 memory stick is supplied (which also includes bonus ringtones, graphics and animated screensavers).
The organiser mode exceeds all expectations with a calender, no less than 5 alarms, calculator, timer, stopwatch and there's a handy LED light providing a useful torch.
I travel frequently and enjoy browsing maps. To my surprise, Sony have come up trumps once again by including Google Maps and a GPS location facility on the phone so wherever I am I can always access a map of any area and zoom in/out to the level of detail required, together with on-screen directions to another location.
Navigation throughout the mass of quality and useful features is both simple and logical with clear menu screens and a crystal clear display.
With all these features packed in a compact unit, it's almost possible to overlook the fact that the Sony K770i is actually a phone and, once again it excels. Internet browsing, email, predictive text messaging, video calls and even ordinary almost old fashioned voice telephone calls are available. Used as a phone, battery life is good, the sound is clear and bright and the phone simply cannot be faulted.
It's quite incredible that so much can be packed into such a small, neat, well-designed package but this is what Sony do best - and they've excelled themselves once again with the K770i. A highly recommended purchase.
