Uh, there is, etuoyo! Nokia Messaging is PUSH email, and Ovi Contacts is its IM offering, and works just fine on the N900. http://betalabs.nokia.com/betas/view/contacts-ovi That link is for Symbian devices, and its no longer a Beta Labs project, but it is available via Conversations on the N900. Ovi is Nokia's service arm. But honestly, with support for all of the common IM service protocols, why must there be a Nokia only protocol? Nokia is trying to enable more people to use their services, not just Nokia users. I think Blackberry is pretty stupid for doing that without porting it to other OSes. At least WinMo, since they were just as common in the business world. In the US, you can get unlimited web browsing, but it isn't free, and neither is it with a Blackberry. Usually, there is a fee for BIS access. Nokia doesn't control service, though, the carriers do that. But I've used unlimited web access on my mobiles for years. All your friends have email, right? Why not talk via email, or tell them to install a more common IM client? Makes sense to me. BB Messenger is just a gimmick. It's a closed IM protocol and not worth much. I'd get the N900 and call or SMS them if its that important.
