I noticed a strange thing since updating iOS to 5.1.
Pretty much none of the apps I buy or update get installed instantly. They are often left hanging in "Waiting…" mode for several hours until they get installed. I can stop the "Waiting…" process by removing the app and trying to install it again, but it still waits for a while until it installs.
This never happened before as apps used to get installed instantly. Is this normal in newer iOS version or is there something wrong?
PS. This is happening on WiFi.

I had the same problem after upgrading to iOS 5.1. In addition to the issues you mentioned, the Music app got really slow after start up, taking up to 10 seconds to respond to my taps and touch gestures.
As I couldn’t find a simple solution to the problem, I ended up restoring my iPhone to factory defaults (this is basically a clean iOS 5.1 install) and started over. This fixed my problem.
Update: Seems like there is a workaround:
