Review: HTC Thunderbolt
Apps
The Thunderbolt can access all of the apps in the Android Market and more. Support for Android is not lacking. If you want apps, they are out there. One thing that stinks, though, is that Verizon Wireless has installed tons of bloatware on the Thunderbolt. This bloatware can't be uninstalled and eats up the amount of memory users have for their own apps. There are 52 apps on the phone out of the box. That's kind of ridiculous.
Bluetooth
The Thunderbolt can connect with mono and stereo headsets with no problems. I didn't encounter any issues when pairing different devices, and sound quality through both mono and stereo headsets was quite good. The Thunderbolt can also be used to push pictures (and other files) between devices, such as PCs or other phones.
Clock
When you wake the Thunderbolt from sleep, the time is easy to find and read. There are a host of different digital and analog clock faces from which users can pick. The HTC Clock app is off the hook. Basically, every clock-related function you can think of is packed in, such as stopwatch, countdown timer alarms, world clocks, etc. The weather is thrown in for good measure. It looks classy and is a breeze to use.
GPS
Both VZNavigator and Google Maps are installed on the Thunderbolt out of the box. Both offer voice-guided turn-by-turn directions between points, and can re-route you if you get lost. Google Maps 5.0 is particularly impressive because it now offers offline use (in case you roam out of network coverage) as well as 3D maps for a limited number of cities. The VZNavigator software is very good, but it costs $10 per month to use.
