Four handsets with the 4G moniker in their names were recently tested by MSNBC for download speeds. This includes the pre-production Galaxy S 4G due at T-Mobile, the currently available myTouch 4G from the same provider, the Sprint HTC Evo Shift 4G and AT&T's HTC Inspire 4G, along with the AT&T iPhone 4 that runs on 3G networks. The experiment found that not all 4G-labeled devices deliver the same kind of performance, which is what leads to consumer confusion.
