Mundu has released their product for Sony Ericcson - has anyone tried to hack the install for their Blackberry and if so, what has the outcome been?

It's a great product with a MUCH MORE attractive price point that JiveTalk (again, WONDERFUL app, but pretty pricey for IM)....

I've attached the jad and jar files (.zip) for the Sony install if anyone wants to take a crack (no pun intended!) at it...

Thanks!
