Fring for iphone client update – push included – update: push cancelled

Fring just updated its iPod touch/iPhone client to include push notifications. Anyone have a line on a SIP service that supports notifications (ringing) via push?

update: Apparently push was cancelled at the last minute according to the fring blog

“As some of you might have noticed, originally this latest version was to include Apple’s new Push Notification feature, which was later disabled due to some technical difficulties and will be available on fring’s next iPhone version, currently submitted to the AppStore. Stay tuned!”
