I updated the other day.. on my 8830, and everything is MINT.. no problems what so ever, the new L theme is great, and the media center looks great too, ALSO the mic recorder is perfect for making self notes or recording lectures!

I also noted that the problem i was having with making calls has fixed itself ! and the phone works ALOT smoother and quicker !

amazing upgrade from version 4.2 imo ..

FYI : i did the upgrade through DTM, not from the link above, dont know if that makes a difference or not ..
