Phones on Novells certified list are phones that supports the Intellisync client. Where do I find information about what SyncML versions GMS supports?

Sony Ericsson K700i works fine, but it is not on the certified list. I have tried to sync with Sony Ericsson K610i, it supports both SyncML 1.1 and 1.2. In 1.1 mode it syncs contacts an tasks but not calendar.
