Darn it, just looking at picks for the new phone and it seems that the new flash will be a problem with the cut outs on the Fre case. I don't really feel like spending another $80 for a case
I don't know about the Fre because I don't have one but with the LifeProof Nuud both of the flashes fit in the same cutout. You can't use the touch id but I don't use it anyways. So you may still be able to use it.
Lifeproof is working on a new case for the 5s. They certainly wouldn't be wasting time and money if the case was compatible. They did not change anything with the 4 to the 4s. I know it stinks cause the cases are so expensive. My only advise would be to sell it with the 5.
