When I swapped sims, I had a better look at damage to my travel phone. Noticed it a couple days into the trip. I don't remember dropping it or anything.

Not clear what is going on here, the phone still works.

@feorlen That's *extremely* bad (as in, fire/explosion-hazard bad) and you should shut it down and get it to an Apple Store ASAP.
@boredzo @peemee @heyitsgeo The repair shop should be able to handle it, they have replaced the battery in this phone before. I've got an appointment for Monday.
@feorlen sorry I missed the notifications. Glad you are getting it fixed!
