Resolved iPhone 5 (Verizon) jumping between 3G and LTE after drop

Ok, normally I would think I was just having service issues with Verizon, but it almost never happens at home. Basically I was out and about today and accidentally dropped my phone in a store. I have an otterbox defender, and this is probably the first time I've really dropped it. I didn't really notice it at first, but my phone is not really receiving LTE anymore. I can intermittently get it, but I'm mostly on 3G now. Normally I don't have issues getting LTE in the Kansas City area. Perhaps I'm just being paranoid, but I worry that maybe the antenna was damaged or something. I've tried switching to airplane mode and back as well as turning the phone off and on again. I have AppleCare +. Anything think it's worth a trip to the Apple Store?

 

Hmm. Maybe Verizon can test it. Their store is much closer than Apple. I'd rather not have a 3rd party open it up in case that voids the warranty.

 

It shows no signs of damage on the outside. The otterbox did its job of protecting the glass.

 

Verizon store didn't seem to think that anything was wrong with it. Told me to reset the network settings. Seems to be working for now. If it comes back I may take it in to Apple.
