Before you head out Friday to upgrade to a new iPhone 3G be sure you take a minute and test the speed on your old iphone. It will be interesting to compare the before and after speeds. You can visit http://testmyiphone.com and measure your speed as well as compare to the last 100 people who tested. If you want to test it at multiple places, I noticed Patrick over at Justanotheriphoneblog has a nice run down of a few more online speed test places as well.
