I got out of FTM the other day by simply turning standalone mode on then off:
Menu / Settings & Tools / System / Standalone Mode.
It's Factory Test Mode, and is supposedly a very good way to turn your phone into a brick. For what it's worth, the QPST FTM App help file says:
The Factory Test Mode (FTM) Radio Frequency (RF) Evaluation Graphical User Interface (GUI) software is used to to test a phone. FTM RF Evaluation GUI is an application used to control a QUALCOMM phone such as a Subscriber Unit Reference Design (SURF) or Form Factor Accurate (FFA) for testing RF in three system modes—CDMA 1x, GSM, and WCDMA.
This application requires Dual-Mode Subscriber Station (DMSS) or Advanced Mode Subscriber Software (AMSS) software with FTM built into it. The FTM mode must be enabled before using the CDMA 1x, GSM, and WCDMA RF controls.
FTM is a mode of operation that allows a user to perform diagnostic or design verification functionality by exposing functions not discretely available to the user in DMSS mode. FTM does not provide the ability to make phone calls and is not driven by the DMSS Call Processing State Machine.
