Coming from the HTC Rezound, one thing I really liked about it was how I could link all my social media contacts. On the GS4, I can't seem to be able to add Twitter profiles to my contacts. Anyone know of a way to do it? Tried using TweetCaster since I sync my Facebook contacts through FriendCaster, but didn't see an option to sync the contacts. Another thing I noticed it that one past phones I had a "desktop dock" mode & a "car dock" mode, where on this it only seems to have one dock mode. Is there a way to have the desk clock launch when I put it in my desktop dock at night & launch my car app (iBolt's app) when I have it in my car dock? Otherwise, really liking the S4 so far. Granted today was the first day & I spent most of it setting the phone to my liking.
