What could possibly come after the 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.
