yes, it works at least with my T68i. Also the USB cable for the t68i (which is also charging the phone) works well with P800. I am therefore not using my docking station anymore as I like my P800 getting charged via USB while sync.
Sorry.. the sync station only works with SyncML enabled Ericsson phones... the R520, T39, T68m and T68i, and the P800 are the only ones that sync properly.
I don't the R600, T65, T100, T200 and T600 can sync with Outlook... unless they came with their own PIM software for the PC, then you can use the sync cradle of the P800, or the data cables.
