Wi-Fi & 3G Data Connection Problems Surface After iOS 4.3.3 Update

A number of users are reporting problems with Wi-Fi or 3G data connections after upgrading their iPhones to iOS 4.3.3. I’ve encountered the problem myself on 3G and a friend called me the other day to complain to me about the problem on both Wi-Fi and 3G. He was pretty frustrated about it and I cannot blame him since it seemed to come and go for him.

You’ll notice the problem manifest itself whenever you try to access a network resource and the busy indicator to the right of the carrier signal label seems to get stuck and nothing happens – mail isn’t downloaded, a web page doesn’t load, etc. I haven’t noticed the problem on my iPad 2 nor have I seen people complain about it happening on their iPads.
