What if, instead of iPhone 5 or iPhone 4S, Apple decided to call the new device iPhone 4GS? Confession: I used to love those old Marvel What If? comics, like what if Captain America were discovered today, or what if Conan appeared in the 20th century, or what if Jean Grey didn't die? (You know, before they retconned that into reality.)
So let's pretend for a moment that there's no big new redesign this year and that means Apple doesn't want to go with iPhone 5 as the name, and iPhone 4S just doesn't do it for carriers who, now touting HPSA+ as 4G are eager to slap that faux-logo on every box they can. AT&T and others would almost certainly want to market an HSPA+ iPhone as 4G, the way they do their other HSPA+ phones, so having 4G or 4GS in the name would be perfect for them.
