iPhone 3GS? The iPhone 3GSS, of course! Joking aside, turns out Apple's already dropped the 4G bomb on one of its job postings in May 2009 while seeking for a "Cellular Technology Software Manager" with "expert knowledge of... WCDMA/UMTS, HSPA, HSPA+, LTE etc." That's right, LTE. Now, we're not saying this means a 4G-powered iPhone is next in line in the annual product cycle, nor does this listing confirm Apple's favored 4G radio (be it a decoy or an eventual change of heart), but given AT&T's interest in LTE plus its prolonged love affair with Cupertino, it's pretty hard to not consider LTE as a realistic option on future Apple portables. Frankly, it won't be the end of the world if a 4G iPhone fails to turn up this summer -- most of us here would rather have something with improved battery life, real multitasking, and 720p camera over those insane data speeds. No, really.
