If you managed to pass over the errors displayed by iTunes during the restore process to iOS 5, you now have an updated iDevice that probably exhibits some problems that you did not have on iOS 4. Either certain applications have not been installed, or certain functions have disappeared or others are not working, everything happens for a reason and they all have a solution. Problems like this occur when you install a backup of iOS 4 on iOS 5 because we are talking about 2 different operating systems and it is normal for these kinds of problems to occur. Every year, there were a huge number of users who complained that an update from iOS x to iOS x left them with problems and it all stems from the backups made by iTunes for our terminals.
Considering that there are many problems that can arise, I cannot cover them all in one article, but I can answer your questions. If you have problems after updating to iOS 5, please leave a comment and I will help you solve them. Please summarize your problem in a single comment.
