Gotta say, my experience with Skype on the ppc is poor at best. I tried the original alpha/beta about a year ago, on hx4700 and treo 700w, with a Bluetooth headset, on both system is worked fine for a little while, read minutes and then BOOM it would lock up.

I have tried the official 2.0 release, and a couple since then, all with similar results. Either, the BT headset interface is messing with the stack on the device, or the app is a huge memory hog. Regardless, it is gone from ALL my devices for now.
