Apple had safer iPhone G4 prototypes incase iPhone HD was delayed?
Another page to be filed in our increasingly full "things analysts say which may or may not be so" drawer says Apple wasn't sure whether or not the N90 "iPhone HD" prototype would be ready to launch and so had a safer, more iPhone 3GS-like N91 in the wings:
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.
That resolution being the 960x640 we've heard rumored for a while, which is a magic number exactly twice vertical and horizontal to the current 480x320 iPhone and iPod touch resolution at pretty much the same physical size. That means existing apps will look virtually identical while new apps look even sharper -- no iPad-style chunky double fuzzies here. Likewise, if Apple wanted to introduce a larger, HTC HD2 or Incredible sized display later, that pixel density would still look great and still mean no work, no fracture for developers.
Other tidbits include:
- No AMOLED as they cost 3x as much and suppliers simply couldn't produce enough to meet the unit numbers Apple sells.
- Apple A4 based on ARM Cortex A8 as the A9 won't be ready until the end of the year, after the iPhone launch.
- Probably 512MB of RAM, though Apple has requested tests on both 256 and 512. (Dear Apple, we'd really like 512 please).
Again, we never know how reliable any of this will turn out to be, b
