If Apple's goal is for people to buy iPhone 4's right up to the announcement of the next phone, which it is, then it makes sense that Apple's Rumor Ministry would leak out confusing "tips" like this periodically to cover up any imminent new product launch, which it does.
Does it really work though? I mean sure a lot of you have the money to buy an iPhone 5 even if you just bought an iPhone 4 the day before, but iPhones are awfully popular amongst college students (around here at least) who can't do that.
I never buy an Apple product more than six months past its launch, since half its usable life is already gone.
I'm starting to think Apple's just gonna stick with the iPhone 4 for another year. Meanwhile, I'm going to have to stick with my 3GS. I'm not going to tie myself down to another two-year contract for something that doesn't have an A5.
