I just found PodTrapper, and it seems to be working pretty well--I really like the automagical podcast delivery. I have run into a bug:
I went to exit the application this morning, and the "Please wait while data is being saved" counter is at about 25000, and if the progress bar is accurate, it looks like it might reach 100000. For background, I added four new podcasts last night and they updated overnight without issue, I deleted one this morning, and 3 of the 8 currently downloaded podcasts are paused. I have a 1 GB uSD card that is mostly empty, and I am using an 8330 with 4.5.0.97 on Verizon.
