I'm sure it's already been suggested, but I'd like to throw my hat into the ring as well. With faster AT&T data speeds being a talking point of the last keynote and with AT&T stating "See why your new iPhone 4S and AT&T's 4G network are a winning combination", I'd like to see some sort of status bar indication of when I'm on "4G". I'm not going to argue whether or not this is 3.5G or 4G. I don't care. Just a simple "plus" next to the 3G icon in 5.0.1/5.1 would suffice.
