Okay, that confirms that you're seeing the infamous AppleSocHot: Hot Hot Hot kernel panic, all right. User Alisha (@flannelist) has written what appears to be the definitive guide to Apple kernel panics and that particular panic is included. Here's what their [[iPhone Kernel Panics|wiki article|new_window=true]] has to say about it.

Sometimes software developers have more fun coding in what occurs in times of error than other things because they are likely to be the only ones that see them. This error is pretty straight forward. Your CPU is not just hot—it's Hot Hot Hot.
* This specific panic refers to an electrical line between the Power Management chip and the CPU. It could in fact mean your CPU is getting too hot. It could also mean, a board level issue with this line.
* Regardless of the specifics, this is almost certainly a logic board issue, not a parts problem.[/quote]
All of which is definitely not good news, as board level repairs are beyond the capabilities of 99% of us home DIY-ers. Not to say it's hopeless, because it's still well worth your time to try some software solutions first before resigning yourself to taking it to a repair shop. Here's a post on the Apple forums from someone who claims to have fixed the issue on their phone by doing a backup and restore of the phone.
