How can i understand panic plist in iPhone 4s?

I have problem - my iPhone 4S (ECID 387220092299 SN DNPH9H44DTD1 software ver 10A523) every time reboot. It can lay shuted down for some hours and i can turn it on only by holding home and lock buttons same time. i have installed xcode 4.5 on my Mac and can read panic lists or errors log but understand nothing.

Did anyone can help me or say who should i ask?

Here is a part of one panic.plist:
