I am in Israel now and I have had time to really test out my iPhone using local ISP speeds but why not post the speed results I get on my iPhone in Israel.

Here is a speed test result set from the Speed Test app for the iPhone:

3G Speed in Israel

The first 3G result set is the 3G speeds I am getting in Israel. Max 471 down and 181 up. The WiFi result, directly under that is my brother's wifi connection, which is slower than the 3G at a max of 440 (average of 138) down and 53 up. You can see, I ran it twice and the speed is more like 140 down, which is much less than the 3G network here. The next 3G result is from New York area, which is about the same as in Israel.

Speed Test

Here is a later subset of results that shows speeds much higher. In some locations in the US, the 3G network got as fast as 1120 down. But my FiOS connection is super fast showing 5764 down and 3049 up, which is slower then my previous report of 12664 down and 3149 up.
