I'm a layman, but I can see that the following components are damaged:
Volume rocker / power button ribbon torn at the power button side
Antennae torn off completely (ribbon cable intact), square grey segments left behind on the battery
Camera ribbon detached from circuit board but seems to be intact
Random black tape torn off
Needless to say, with a busted phone, void warranty, and wife in tears... I need some help from XDA. What are my options? Repair it myself? Take it to a shop? Call it a loss and buy a Nexus off-contract? We don't have any upgrades left and can't really afford to buy a new smartphone at full price.
I uploaded photos of the damage to imgur, but I guess I don't have enough posts to supply the link. I uploaded them as attachments, hope that works.
