I didn't find any threads talking about my problem, so forgive me if I missed one. After upgrading to iOS 4, whenever I went into Safari, it took a few minutes to reload my last page, but now it started just bugging out for a few minutes and giving me a new blank page. And then after browsing for not that long it crashes and usually messes up my whole device. I then have to set it down and wait until it gets a hold of itself and returns to an unfrozen state. I reset the network settings on the device itself many times, and I restored the device once already. Anybody having similar problems? Not just the super slow switching between tabs, but complete application crashing and device freezing.
