Just swapped from Bold to Curve with OS upgrade from 6 to 7 ... and it is a big mess.
I have to reinstall all my Apps, and for each of them it takes ages (stays a long tim in installing state ... so not a network problem) and on top of this I have to reboot after each installation ... like withthe old "good" time with Windows !
Furter the keyboard feeling from Bold to Curve is not really an improvment.
I was liking the BB because I like/need a keyboard ... but having already an iTouch I mus say that the user experience is much better !!!!
So please Mister BB .... make an effort ... or you are dead I guess .....
