The next iPhone needs iChat. It’s 2010. Make it happen Jobs!!
Make it run in the background, or at least have it support push for receiving new messages (unobtrusively). Oh yeah, put in a front facing cam too, and lock video chat down to wifi at first so AT&T doesn’t cry like the babies they are. Then we’ll hack it so it works over 3G. Thanks, that is all.
Ps – your interface is looking dated, and notifications still suck. iPhone OS 4 helps, but Windows 7 mobile is the new standard for UI design (ahem, Zune!), and Droid’s notification stack eats your lunch.
