4G was a big issue with me... I want something much faster. The 4S doesn't have 4G capability BUT it downloads near 4G speeds 14.4 MBS, and this is using a 3G network. Granted it's NOT 4G LTE speed but it is much better than the iPhone4. I also like the better camera, HD video, and especially SIRI
... that's a game changer IMO. The other stuff (world phone) is good too, so I'll probably jump from my 3GS instead of waiting another 10-12 months ! I don't think they'll have a iPhone5 until next summer at the earliest.
I know the market (investors) was disappointed, but I think the AT&T CEO hit the nail on the head. They had the same reaction with the 3GS, and it turned out to be a very under-rated iPhone, which you can STILL get today !
Anyone know how the iPhone4S compares say with a Droid 4G phone for downloads and speed? I was shocked to see the Droid camera speed. Is it really that slow?
