iBooks 1.2 Configuration problem while opening books

Ok so here is the latest of the issues that I have faced since updating the iBooks on my iPhone to 1.2, ok I know it is so damn slow, anyways as you can see in the image below each time I try to open a book I get this msg:

"There is a problem with the configuration of your iPhone. Please restore with iTunes and reinstall iBooks."

Cannot connect to iTunes store while trying to update an app

Ok today's fix is faced by a lot of people on all iDevices (iPhone, iPad, and iPod) this problem occurs sometimes when you try to update an app through the app store and although you enter the correct credentials still you get this problem.

Misconceptions:
1- That this problem is caused by carrier restrictions.
2- That this problem is caused by 3G or WiFi.
3- That this problem is caused by the latest update or backup you made.
4- That this problem is caused by the jailbreak or unlock.
