Hey vickimasor, thanks for posting with us.
Covers are always a matter of debate; I can recommend the Otterbox. Here's a list of the "Carry & Protect" accessories for your device available through our site: http://bit.ly/16nVPye.
Hope this info helps; please advise if we can help with anything else. Thanks!

If you don't mind adding alittle bulk to your phone I suggest the Otterbox Defender granted people say that "You only need the Defender if your into extreme sports or construction." However I like having the extra protection.
