It's the greatest 'on / off' saga of the modern digital age and right now, the possibility of getting a white iPhone 4 has never been so remote.Just to recap, there was originally a three-week delay, followed not long after by a delay for 'months', said to be down to the glass screen and paint thickness. No, we can't fathom that one out either. But just in case you harboured hopes of seeing one for Christmas, Apple has just burst that bubble too.According to Digital Daily, Apple has made another statement, pushing the arrival date well into 2011: 'We’re sorry to disappoint customers waiting for the white iPhone yet again, but we’ve decided to delay its release until this spring.'Yes, that's right, it's now back to spring. Perhaps there comes a point for Apple to scrap the idea of a white iPhone altogether. We think that point is rapidly approaching. Indeed, if that spring date does slip, there's a chance we could see an iPhone 5 before the white iPhone 4. Alternatively, Apple could just release the next iPhone in white only, making the most of all that work getting it right. Just a thought.
