I have to say that this tweak is the cats meow. Now that I have it I do not know how i functioned before it existed. I hate being in an app or typing an email and getting interrupted by an incoming call. Yes it only last for a little bit and most apps will resume but I hate the intrusion. Well that is solved as Callbar changes the incoming call to a status bar sized alert bar at the top of the screen to which I can answer or decline and continue about my businesss uninterrupted. Definitely in my list of must haves.
