I have a Symbian OS phone (Nokia X6) and I have contacts information, last calls, notes reader, calendar and bluetooth music. Not able to have internet connection via bluetooth tethering on this phone, but wife's Nokia N97 works a charm with everything (which is strange as I think it runs the same version of Symbian as the X6)...

And why do you say Apple is the standard? There is not one office function working with the Iphone... at least that's what they say on their page... let's drop this mania of Apple being around everywhere...
