The apps themselves are broken? Really?
First of all, FriendStream can go die. I wouldn't go back to it even if hell froze over. I use
Pure Messenger Widget.
It's not free but it's one of the best widgets I've ever used.
Also, FriendStream does some damage on your battery life. I'm trying my best to slowly turn my back on all Sense widgets. The only thing I use it for is Calendar.
It's very strange that these apps themselves have broken on you. Are you sure you're not referring to just the widgets? (I know Peep has no widget)
If the widget is whats your problem. Delete the widget (Your data will go no where, it's just a widget) and then add the widget back. This will fix your problem.
I had 19 widgets crap out on me with this update, so I know how it feels, lol.
