The XOSkins guys responded to an email I sent about this...apparently they make one for a "case-fit" which is a bit shorter...they are sending me out another, longer version, for free...GOOD CS!
After having this on my phone today, I can honestly say it is a really quality product (just a tad short, but still ok)...I recommend it, but just order the non case one; which will work just fine with a case as far as I can tell!
Better quality than others that I have tried
