Some iPhone developers reported that the recently released iOS4 is not performing well with iPhone 3G model. Responding to this issue, Apple has confirmed that their engineers are analyzing the issues and these problems will be fixed very soon.

The iPhone 3G does not allow multi-tasking. It has resulted in limited access to the features of iOS4 in the 3G model. Further reports have confirmed that iPhone 3G users are facing a very slow processing in their devices after updating it with iOS4.

However, it has been observed that the new iOS 4.1 Beta is performing little better on this model and we can expect that the performance will be even better with the stable release of iOS 4 next time. It can also be expected that iPhnoe app developers will find their job easier with the new improved version of iOS4.
