I've been told on multiple occassions by an Apple Store Genius that certain things will give away an un-jailbroken phone, but few Geniuses check or even care unless you get to the point where they may send the phone back to the warehouse to be refurbished.
I'd say if you think it'll be sent out and you get a phone-swap, then be careful, otherwise don't stress it.
Heck, I've gotten service with my phone in jailbroken state.
