I have also a piel frama for my iphone 4 also i have SGP Neo Hybrid matte,pixelskin HD and Candyshell.The cases i use mostly are piel frama and SGP.The first because of the great protection feeling i get and quality of course and SGP because is so thin and pretty.I don't prefer the cases from speck because pixelskin is rev2(hard case,clicking sounds when i hold her)and candyshell is thick and with a very sensitive back(great protection by the way).
