One thing both sources agree on is that we're not going to hear another peep about thewhite iPhone 4 until next March. That's when Apple will either finally sell it, or push back the release date again until summer and quietly let it die. But with Apple releasing a new iPhone like clockwork every June/July, even if the iPhone 4 does hit the shelves it'll be old news—though appealingly discounted—in a matter of months.
Who would buy one then instead of just sticking it out for iPhone 5? And what incentive is there for Apple to crank on a lame duck device?
So for all the rumors about why and when and how the white iPhone 4 might or might not come out, the calendar's been pushed so far back that by now the point's pretty much moot.
