We have been excited about the arrival of a new iPhone for months now, but if new rumours are to be believed, we could well be getting worked up over very little. It all comes down to who you believe.Let's deal with the good stuff first though. According to Mac Rumors, analyst Ming-Chi Kuo claims that Apple is scheduled to send the 'golden master version' (that's the finished version) of iOS 5 to its iPhone and iPod touch assembling partners between 23-30 September, suggesting a launch for the new iPhone of around mid-October. You've got to give the folk in the factories chance to put hardware and software together, after all. We recently heard 21 October, which is sounding more 'right' by the day.So what about the phone? Well, the same analyst says he has seen no evidence of a fully-redesigned iPhone 5. He's saying a halfway house going by the name of the iPhone 4S is the launch model. Now, he could be telling it as it is, or Apple is keeping the iPhone 5 under tight security after a bit of a lapse last time out. But it doesn't sound good for an all-new model.In terms of detail, he says the new model will have a similar shape to the current phone, with a glass front and back, the same screen size, 512MB RAM and possibly a new camera, courtesy of Sony. Not really what we'd hoped for. But at least there's a new operating system, right? Mind you, that's going to be available to iPhone 4 users too, so not the biggest incentive to upgrade if all of this is correct.All should be revealed in the coming weeks. In the meantime, you might want to cancel that order for party poppers and streamers – it sounds like the iPhone party will be a more low-key affair this time.
