This post from one annoyed T-mobile user is corroborated by numerous other Samsung Galaxy S2 users. In my household we have 2 Galaxy S2 Skyrockets. Both had testfile and one had MTC. A reboot of one of the devices cleared the programs out, but the second device still shows the testfile application installed."
