msn its possible for 7650??

If you mean MSN messenger, no it is not at his time! If you mean msn mail it is possible though wap from mobile.msn.com

is msn messenger ever gonna be possible? coz the wap connection is too slow for live chat like that.

yes. it's possible.
look at http://shapeservices.de.
version 2.0 will support MSN.
now beta-testing of version 2.0 started.... so wait for one week

Yeah, I spoke to the writers of IM+ and they said they expected v2.0 to be on sale this week, fingers crossed! I'm really looking forward to it.
