I posted about my iPhone experience
in April, 2008. I just picked up a 3gs, and I have to say that I am incredibly pleased. Just about every complaint that I had in that original article has been addressed. In addition, the speed increase really is significant. It really is that noticeable. Add in the cool camera upgrades (better pixels, video, and cool touch to focus), and this is absolutely a winner.
The current complaints deal with lack of MMS and tethering, but that's hardly Apple's fault. (Nice workaround for tethering posted here
.) The experience ordering business phones through AT&T sucked as bad as anything I've ever dealt with, so it's not shocking they don't care about their users enough to enable simple features such as these.
Now I just need to find an iPhone app to follow the Tour de France. Allez!
