iSync & SE P800, P900 compatability


Apple Virgin
Hi there.
I've won a P800 and a P900 on eBay and was wondering if they're both compatable with iSync?
My wife may be keeping the P800 and me the P900.
I've never had any problems with previous SE phones (T610, Z600, K700i) so i'm assuming that the PXXX series are okay?
