Bluetooth GPS hoses up on OS 4.2.X

[LiteWait]

I've pasted a simple application that stops getting fixes from a bluetooth GPS unit when it goes out of range or turned off... and then is turned back on/comes back in range. This is a one-shot TimerTask-based LocationProvider.getLocation that will return timeouts forever after the condition occurs. Pearl 8100/Globalsat BT-368i with OS 4.2.1. I have tested this with OS 4.5.0 (beta) and it DOES work there, but isn't a workable solution to require all my target customers to install a beta OS. Should be a simple test, could anyone spend 5 minutes and try this app out or lend some advice? Thanks!
