There’s been a number of rumors about the upcoming iPhone, which most people assume will be announced in less than a week. It looks like a high-resolution 960×640 IPS LCD screen will be there, as will a front-facing camera for self portraits and video calling. Many details are still not clear, but I predict we’ll see this model in the same three sizes as the iPad: 16 GB, 32 GB, and 64 GB. It will be available in black and white. It will have a new design with a flat black and metal controls. It will have a 5 megapixel camera with a flash.

The real unknown is the name. The most likely contenders are iPhone HD, iPhone 4G, and iPhone 4.

iPhone HD has been a popular name – it emphasizes the high res screen and presumably the ability to record HD video. It makes sense as a name, but doesn’t really address the front facing camera. I think it’s reasonably likely.

iPhone 4G was tossed around in the police reports surrounding Apple’s missing prototype, though that doesn’t mean Apple will use that name when the final phone is released. The problem is that it implies that the iPhone will use a “4G” network, which it will almost certainly not since these are largely not available yet.

iPhone 4 avoids the misleading aspects of “4G”, but runs the risk of confusion with the 4th version of the operating system, iPhone OS 4.0. I haven’t seen anyone use this name, but I think it’s reasonably likely.

All these names are equally likely in my mind, but I’d probably favor iPhone HD.
