Today, I went to the greenbelt AT&T center. 1 hours later, I steped out the shop with an iPhone in hand. I bought a 4gb iPhone at the expense of $520 including the tax.

After the complex process of activation, I get the very first experience with iPhone.

First, the screen is amazing. Amazing in size and quality. A very big screen.
Second, the device is very slim.
Third, about the input keyboard, it is very smart, it can correct the wrong letter automatically. But no chinese input is not good.
Fourth, the camera is quite good.
Fifth, some emails those are not encode in UTF-8 will not display correctly, especially in chinese.
Sixth, gprs connection in us is much faster than in china. I even watch Youtube via GPRS.
Seventh, all the widgets are very useful.

In total, it is a good phone for me, a perfect phone for americans.
