> The 3D, the blur, the compositing – all of them are disabled or degraded on the [iPhone 4's] A4.
I hadn't heard that before, and it's quite interesting. Does anyone know if previous iOS versions have similar feature segmentation, other than the obvious (and perhaps artificial) ones like Siri and 3d maps?
Besides what others have already mentioned, third party devs (including myself) find ourselves disabling features on the iPhone 4 also.
The important thing to recall is that the iPhone 4 quadrupled the number of pixels you had to render while doing almost nothing for CPU performance. Graphics performance-wise the iPhone 4 was a huge downgrade from the 3GS.
If you're doing any sort of graphics work that's CPU-bound, your iPhone 4 performance is going to be dismal.
Background apps was a pretty big one when iOS4 came out, and couldn't run on the 3G. (I actually jailbroke to get the feature, and it was painfully slow)
