i just got an iphone 16gb from my girlfriend...2 weeks ago. i recently had a nice conversation w/a tech guy who came to our house to install att cable and internet service who had an iphone and said our iphones are already 3g capable.2)the new iphone may need to unlocked diffferently(i don't know that)i have t-mobile...in the us.3)i think the new version is cheaper in construction.this seems like iphone 1.75...i think mine is more like 1.5...being 16 gb.gps is cool but not worth buying a new one...4)and also...read the info at the apple iphone page,its say that price is good w/new 2 year activation....w/att. i may buy one down the line...but doubtful...i love my current one! i could try to take this one back,if i really wanted to but...why? somebody is going to create a 3g app if the tech guy was wrong which,i doubt he was anyway!i am exited about the new .mac and some of the software apps tho.
