God, Apple is so focused on shoveling crap down our throats that they forgot that this device is a phone first and everything else is secondary. They just need to fix the dropped calls problem and core "Phone" functionality first, then they should go ahead and add the gravy. If the next update doesn't fix the phone I'm done with this so-called phone.
I find the 'phone' part works well. Never had a dropped call. After 2.1 the signal became much better, not that it was bad before. Those are my experiences.....
