What a piece of work this thing is...
It arrived at 9:43AM and I made my first call at 10:00AM. I have owned many cell phones and rarely used any features because of trying to find the right buttons or just plain could not be bothered to fool with finding out how to do things. No more!. Without reading anything other than watching some videos on the Apple site, I activated the phone in less than 3 minutes, sync'd my Bookmarks, Contacts, photos and iTune library (my favorites) in less than 5 more and I was up and running.
It is comfortable in your hand and has a very solid feel to it. The sound has been fine and my hearing is stressed so to speak. Music sounds fine using the earpiece. Finding the functions is nothing more than touching the right icon. The touchscreen is very sensitive and it will take a little time to get a routine going...I touch type at about 50-70 words a minute so this will be a change for me. I have not tried the BT connection with my Moto H700 earpiece yet. I will not use it in the car since I have my RAZR integrated with COMAND and never take it out of the cradle.
I will add more as I use it more but those familiar with Apple products understand when I say "it just works!" I am sure that many of the features that some say are missing will show up in software updates on a regular basis.
