A Apple insider said the N90 “codename for iPhone HD” may not be ready for launch yet. If so, Apple has an alternative “safer” iPhone with the codename N91. It will have less functions than the N90 and will probably not include the front facing camera. Its just like the iPod Touch where Apple removed the camera just before Steve announced it on the Keynote.

On a side note, Apple initiated the iPhone 4G project at the end of 2008. According to our sources, Apple actually has another product codenamed N91 for the project, which offers less change from previous iPhones compared with the N90. It’s a parallel product to back up the N90 in case there are major delays due to significant modifications in casing, display resolution, digital camera support and so forth. » Apple Has Alternative iPhone Prototype On Hand
