I'm sorry, but Apple does not provide a downgrade path for iOS. Because downgrading is unsupported by Apple we cannot discuss it on these forums, but you can use Google to find information on how to install an older version of iOS on any iDevice.

First, there is no Apple supported method for downgrading software.
The support of specific apps in a particular iOS is the responsibility of the app developer. Not sure of those apps support iOS 6.0.1. You would have to check with them.
What user troubleshooting have you done, in order they are restart, reset, restore from backup, restore as new. Once you have tried all of those options, if it still doesn't work, then you contact Apple for a hardware check.
