Finally I got wipresenter installed – my E90 just cannot send file to my laptop through bluetooth, and stupid Psiloc didn’t offer the direct download of the small exe for Windows, so …
Anyway it’s working now, I didn’t try the presentation feature, but showing things from handset on the computer is pretty cool.
BTW, I was thinking bluetooth trechnology is pretty well standardized, but obviously it is not and seems won’t be in the future.
