I upgraded my 4S to 5.0.1 as soon as I bought it last Friday, and it seems to have problems downloading iCloud contact updates. I update through the Address Book on my Mac, and changes don't replicate to my iPhone, or to my iPad 1. I've removed iCloud contact syncing and set it up again, and it doesn't pull down my contacts at all now. Additionally, I can't go into the body of emails (Gmail Exchange), as it just shows the spinner and says "Loading". I've reset the iPhone, done a factory reset, and even restored the software but still no good. Also, my iPad hasn't downloaded any emails or replicated through the Gmail Exchange servers since I updated that to 5.0.1 a couple of nights ago. On top of that, battery life on both my 4S and my iPad (which was previously fine) is now appalling. All in all it strikes me that, given I'm using 2 different iOS devices and have reset/restored, 5.0.1 was released in a rush with little or no quality control. Am I the only one to get these issues?
