Just immediately after restoring to iOS 6.1 and jailbreak untethered, I re-installed all my apps, connected to the internet. Within minutes, badge of 17 updates showed up on my App Store icon. This means that I have apps that needs to be updated.
Immediately I launched the App Store app, clicked Updates and waited for 5 minutes only to be greeted with a blank white update screen. At first I though my internet connection was the problem or maybe iOS 6.1 had a bug. However, I found out that other people have reported the issue on 6.1.1 and 6.1.2 too.

How To Fix Blank App Store Update Page
Step 1: On your device, first, close Updates from the multi task pane. click onSettings>General>International>Language
Step 2: Change the language from any language there (Bahasa Melayu in my case. It could be British English in your case) to English: Even if you have English, change to another language then back to English again
Step 3: After changing language, launch App Store Updates again and the problem should be resolved.
Step 4: If the above steps didn’t help, go toSettings>General>Date and Time>Set Automatically>Off.
Step 5: Set the date one year ahead (e.g change 2013 to 2014). After doing this, try to update the apps again. You may get an error message
Step 6: Go to date and time settings again and change back to normal time and date by changing Set Automatically to On.
Step 7: Go back to App Store Updates and it should start displaying
Step 8: If the above steps didn’t help either, Go to your Podcasts and off all subscriptions.
Step 9: Go back to App Store Updates and it should start working again.
If all of these methods above still didn’t work, you may have to install your app updates using iTunes and then transfer them to your device.
