IBooks says that it cannot connect to the iTunes store?

Question

iBooks cannot connect to the iTunes store?  If I go to iTunes, it will connect to the store.  Any ideas?

This could be caused by several things.  Please provide more details on how you are connecting to iTunes, i.e. WiFi or 3G.  If WiFi is it your own home connection or a public one?
For example at work there is no real reason for me to connect my iPhone to the company WiFi because they have nearly everything blocked; iTunes, gmail, aol mail, yahoo mail, FaceBook, Twitter.  Basically any of the Fun web sites.  So if I feel the need to update an app while I'm at work I need to wait for lunch go down to the lobby and use the Starbucks WiFi Connection.
But if you are just having a problem connecting to iTunes you might try resetting your network connections, Settings => General => (Scroll to bottom) Reset => Reset Network Settings, wait for phone to restart and connect to the network.
This will just disconnect and reconnect you from your 3G provider and clear out all the junk that has built up in the network buffers.  You will have to reenter your WiFi Passwords when you try to reconnect to them but you should have a cleaner connection.
You can also try restarting your phone.  Press and HOLD both the Home button and the Power button on the top of the phone at the same time for about 10 - 20 seconds.  When the Slide to Power Off screen appears CONTINUE to hold the buttons down.  The screen will go black and then the apple logo should appear.  When the logo appears release both buttons and wait for the phone to restart and reconnect to the network. 
A quick option (Although not as effective as doing a Network Reset) is to turn on Airplan Mode, wait 15 seconds and turn it off.  This breaks the connection with your network provider and then starts it up again.  It just doesn't clean out all the stuff in the buffers, but you may get a better internet connection.
