Seidio is the best one
I have the Seidio and agree with the previous comments. One thing to keep in mind is that if you use the physical keyboard, the Seidio case makes it extremely difficult because it covers part of the top row.
I have the red rubberized case and I love it.. it is not bulky and it works to protect the phone...I tried after market ones mainly so i would have all the colors ect.. and they did not fit correctly they kept popping off. So I bought one at verizon and it fits perfect. LOVE IT
