iPhone 4S users on AT&T’s HSDPA network are getting a little something extra in the new iOS 5.1 update that went live today.

The network indicator now states the phone is on a “4G” network. That replaces the 3G icon that appeared in previous versions of iOS.

Rumors surfaced earlier last year that AT&T wanted Apple to promote its high-speed network as “4G” on the iPhone 4S. T-Mobile also advertises its HSPA+ network as 4G.

The iPhone 4S on AT&T’s HSDPA network is capable of 4G-like speeds, but it isn’t the same as 4G LTE, which is a feature of the new iPad announced today.

What do iPhone 4S users on AT&T think about the change of icons? I could really care less what the phone says, I just want the fastest data speeds possible.
