Wondering what phones 1Z0 035 729B OEM Bluetooth compatible with?

I've currently got the 1Z0 035 729B OEM bluetooth kit installed in my Octy and it works perfectly with my (rather old!) Sony Ericsson W995 - pairs quickly, full phone book access, etc, etc.

As my W995 is starting to show it's age, I'm looking at some kind of upgrade in the not too distant future. Obviously it would be nice to upgrade to something that's much more up to date, but I'm not sure what phones will definitely work with the 729B and to what extent.

Does anyone else have the 729B? What phone(s) are you using with it, and do they work fully? iPhone 4S? Galaxy S2?

I know there's a list of compatible phones in a PDF on here, but I'd like to get some input from people who have actually tried/used their phone with it - successfully or otherwise.

Thanks
