If anybody had problems updating their iphones to IOS8, it could be due to Poker Journal.
If you do use PJ and have not updated to IOS yet... DON'T.
The problem occurs in the actual initial installation of IOS 8 (it freezes).
I then had to restore the iphone again. Once I finally got IOS8 running, and all my apps installed,... Poker Journal was the only app that didn't work.
I spent 2 days trying to get my iphone/PJ working, and then finally found out it's a known error, and the developer is currently working with Apple to fix the problem.
My only solution was to downgrade back to IOS7, and luckily, I was able to get all my sessions back from an icloud restore.
