Buy new iPhone 4S or wait....

No, but just look at the SGS2 numbers. This is on an even faster 21mbps max modem.

You're just not going to get more than mid-single digits regularly with HSPA unless/until you double the bandwidth (i.e. T-Mo's 42mbps version).

Aren't you lucky to get 3Mbps from most 3G phones? Even if the iPhone 4S isn't the fastest HSPA+, it's still HSPA+ and I would imagine doubling the speed is going to be a trivial accomplishment over the iPhone 4. Maybe I'm wrong. Guess we'll see in a few days.

If you have a 4, I'd hold off on the 4s, it's faster etc..., but, you'll kick yourself when the iP5 comes out.

No flipping idea when it'll come out, but I suspect it'll be pretty good...
