Amazed by the speed of 3G

I’m writting this on a laptop with a 3G modem. I’m actually amazed by the speed. I had to get some files from an FTP server. The speed was about 150 Kilobytes / second. I sometimes even have trouble getting that with my adsl account. I had read about the theoretical speeds but had never seen it in action.  Still have to check how fast it goes if I use my iphone as wireless router, should get the same speed IMHO. Anybody tried it yet?
