Review: LG Quantum
The Quantum pairs with mono and stereo headsets with no problem. Sound quality through mono headsets was pretty good for phone calls. Sound quality for music through stereo Bluetooth headsets was also good. The Quantum supports the PBA (phone book access) profile, but it can't pair with computers to pass files back and forth.
It's easy to read the time from the Quantum's lock screen. Press the lock key, and the screen pops to life with a nice digital clock. The time also appears sporadically in the status indicator bar at the top of the screen. I couldn't find any way to adjust the home screen clock behavior, but it works well enough as-is.
The Quantum has AT&T Navigator and Bing Maps on board. AT&T's Navigator software works just as it does on any other device, and I had no problems at all with the Quantum's GPS system. I much preferred Bing Maps. Bing Maps supports pinch-to-zoom, searching, directions, traffic layers, and even satellite views. Of course, Bing Maps is free, but is limited to providing only a list for navigation. AT&T Navigator provides voice-based guidance, through it costs $10 per month.
