It has been a couple of days since I upgraded to 4.0.2 on my iPhone 3G. I have been experiencing the frustrating slowness that makes me think of throwing my phone off the nearest, highest rooftop. I initially thought it was just because of the fresh install, the forced restart, etc. But I didn’t get this kind of degrade performance moving from 4.0 to 4.0.1 so I’m not sure what is the difference this time around. Why is my iPhone 3G working very slow after upgrading to OS 4.0.2? Please advice. Thanks.
