Believe it or not the US has been quite far behind in cellphone technology. Scandinavia's pretty much been pioneer in mobilephones (Nokia in Finland, Ericsson in Sweden). Not many years ago the US was still using NMT networks instead of GSM. So the iPhone is on quite a fresh market of cutting edge mobilephone tech.
Right on, thanks for disabusing me...and it's certainly true that the US has been decidedly behind in the 3G department. I just remember coming to France for the first few times a number of years ago and finding people awed by my very ordinary cell phone (no longer, of course; I like the current arrangement here much better than in the states). Perhaps the delay here was due to the bizarre Minitel system that was common here until not that long ago? I don't really understand how it worked, but I hear it was universal, and that some older folks are a bit lost without it. Somebody should write a dissertation on Minitel and the way it affected communication development in France.
