By now, everyone knows the drill: Apple releases new flagship iPhone designs in even-numbered years (iPhone 3G in 2008, 4 in 2010, 5 in 2012), and follows up with an "S" upgrade in odd years (3GS in 2009, 4S in 2011). We expect 2013 to follow that pattern, with the all-but-certain iPhone 5S hitting in September. While the external design will likely look nearly identical to its predecessor, likely improvements will include a faster processor, possibly a better camera, and (definitely) iOS 7
, which was already previewed in June.
