My hat is off, good job, I like the way GPSLogger works.
It took me a minute to figure out that I had to enter "store/" or "SDCard/" to begin browsing the path to stash the files.
I tested v0.4.2 on two AT&T 8310 Curve's with full cell and data coverage and two AT&T 8820's with no SIM Card. (with custom WiFi connections).
