What phones work?

Hi all-

Bought a 09 750 in March and have yet to make a phone connect. Will pair, but not connect. BMWs "approved" list is hopelessly out of date, dealer says "they have the best luck with iphones". Not very encouraging. I use simple voice & text phones and don't want to upgrade to (another) pricey device I don't need just to make calls. Anyone had some success here?

Thanks

I also have found that the iPhone works best in most BMWs. My 2011 X5 35d and now my 2012 AH7 pair and work flawlessly everytime with my iPhone 4 and 4S!
