Review: Sony Ericsson Vivaz
Apps
The Vivaz has access to AT&T's application center, which is really just for purchasing wallpapers, ringtones, and content such as that. There are other apps available, but they are not the robust applications that are offered to today's smartphones. This is in part because the Vivaz runs an odd branch of Symbian, and it isn't widely supported by U.S. developers. It comes preloaded with several trial games and applications.
Bluetooth
The Vivaz paired with both mono and stereo Bluetooth headsets with ease. Phone calls were decent through a standard headset, though the volume was inconsistent. Music sounded great when played through a stereo Bluetooth speaker accessory. I was able to send photos and other files back and forth between the Vivaz and my computers with minimal fuss. The Bluetooth works fine.
Clock
The Vivaz is not a suitable watch replacement. There's no way to see the time unless it is fully unlocked, as there isn't a clock on the unlock screen at all. Once unlocked, there is a small clock in the black box on the home screen. The problem is, the Vivaz returns to the screen you last used when it is unlocked. For example, if you were browsing the web, the Vivaz goes back to the web page, not letting you see the time on the home screen at all.
GPS
The Vivaz comes with a whole host of GPS-based applications and services. First, it has access to AT&T's for-pay navigation service. It also has AT&T Maps, AT&T Family Locator, Loopt, Where, and several other GPS sports applications. The AT&T Navigation service works fine, but the $10 monthly fee is enough to prevent me from using it. The Family Locator applications lets parents pinpoint their kids' phones on a map.
