Review: HTC One S for T-Mobile
Apps
T-Mobile loaded the S with a bunch of crappy bloatware, such as the T-Mobile Mall, 411, More for Me, etc. Only a handful of the apps can be completely uninstalled, but most of them can be "deactivated." Deactivated apps are removed from the home screen and menu pages and will no longer run, but they remain installed on the device. That's a bummer. Some of the stand-outs include Polaris Office, DropBox (with 25GB of free storage), HTC Hub for HTC-developed apps, and an advanced task manager.
Bluetooth
The S's Bluetooth radio works perfectly. It paired with every device I could find. Phone calls, in particular, sounded like crud when sent through my car's speaker. I blame this on the device's poor phone capabilities, not the Bluetooth. Music sounded very good when sent to stereo Bluetooth headphones, though. I had no issues pushing files to/from the S.
Clock
There are 18 clock widgets on the S. Any of them can be chosen as the home screen clock, but not the lock screen. The clock on the lock screen is a smallish, digital read-out that is positioned at the top of the screen. It is readable at an arm's length, but can be hard to see in bright sunlight if you've chosen the wrong wallpaper.
GPS
The GPS worked flawlessly. The S's GPS radio was able to lock on my position in less than 15 seconds, and was accurate to within about 15 feet. Thanks to the speedy network access, fast application processor, and accurate GPS radio, real-time directions with Google Maps were spot on and as close to "real-time" as I've ever seen from a cell phone.
