I have an iPhone 3G, and have regretted loading ios 4 since the day it came out... The lag is, at times, unbearable. Despite rebooting at least once per day, I often am able to type full sentences before the screen catches up, and have situations where the screen freezes for 15+ seconds. I know Im not the only one experiencing this, and since I wont be in a position to download the new o/s for a couple of days anyway, maybe someone can confirm if its worth it Does ios 4.0.1 address this, at all? Thanks in advance.
