it may be a little premature to conclude the listed apps are not happy w/4g. a better test question is "are the apps that exhibit forced closes simply interacting badly with another app. that is a little hard to determine.
I was having battery problems, wiped the phone, and am back to normal battery use (ablut 24hrs on a charge).
My conclusion: one of the apps I had recently d/l had some runaway processes that caused the battery issue.
my point: software interaction is the most likely cause of forced closures (part of the issue could be some of the newer components of the os (one possibility is the suite of components that enable 4g).
