Recently installed 4.7! WOOOO! Extrememly slow. Feeling confident about RIMM, went ahead and upgraded my phone firmware. 4.7 syncs are extremely slow with only 800 contacts. Also had to uninstall and download media manager version so I could copy photos to my computer! A 200+ mb file!

Followed advise from other guys in this thred, I uninstalled 4.7 (with media manager??), then dowonladed and installed old version 4.3. So far 4.3 with media manager seems to work fine, and fortunately my phone still works after having to step back several versions of desktop manager.

I like really RIMM, but they need to fire the guy who wrote the recent versions of Desktop Manager and re-hire the guy who wrote 4.3.
