I think most users are better off by doing a reflash of the phone once updated.

We probably all have had all sorts of extras-devel apps on our phones, and I suspect that all the various IM plugins etc. might harm the whole 'native Skype experience'.

I don't have the update yet, but I'm gonna reflash my device as soon as it lets me do it in the phone menu. Basically I sometimes had to reflash my 5800XM after software updates to get all the latest features and functions to work (properly).
