This is the ultimate tinker’s phone, and because of this, may be too much for the standard user. It is a great price for a color touch screen phone, and because it runs on android, it supports a lot of apps in the Play Store. This would be a great “road warrior” office phone because of it’s built in VPN capabilities. I especially like the fact that it is virtually un-brickable. Simply load some firmware on to an SD card, insert it into the phone, and boot while holding * and #.
