Jeff from iDownloadBlog is one of the lucky few to have not one, but three iPhone 4S’s running on all three US carriers.
The above video demonstrates the speed differences between AT&T, Verizon, and Sprint on the iPhone 4S. As you can tell, Sprint is painfully slow while AT&T and Verizon seem to have very similar speeds.
Apple touts the iPhone 4S as having HSDPA “4G” speeds on AT&T, but many have found that data speeds on AT&T are barely faster than Verizon’s network.
Also, if you can’t activate your 4S today, you’re not alone. AT&T specifically has been falling apart under the crushing weight of the 200,000 pre-orders that were delivered for its network today.
