I often use SymSMB from Telexy to connect my N95 to my PC and move files back and forth. It like my N95 was just a normal USB drive except no wires. Well, they just released SymSync and basically what it does is automatically transfer files from/to your N95 (or other S60 device). It’s got a cool setting that only does it when its charging.
I like to process my podcast MP3s before I listen to them (I speed them up) so I can’t use the N95’s built-in Podcasting app, as cool as that is. With SymSync, my N95 automatically grabs all of the processed podcasts when I charge it at night. Unbelievably nifty app and its only $11!
