Push email on blackberry

One of my friend has purchased a Blackberry and he wants push email feature. His operator is Telenor and he is using prepaid package. What's the best way to do that?

try Funambol BlackBerry Push Email Client. not so much good but its free and open source.

and if Telenor is providing blackberry specific services like [bIS] to its subscribers than avail that. it will be most good.
