You must have been lucky then Cal. Any griffin things I've had have broken FAR too easily. Cases that cracked without being dropped, a headphone cable thing that frayed and stopped working, even though the cable protection was supposed to be rugged.
I'm waiting on my new marware glide coming for the 4, but in the meantime I'm using my old one, and a sort of harder plastic/silicon jacket thing for the 4 that was cheap off ebay. And always with the screen protector.
How's everyone finding the battery life then? I had to delete and re-add my exchange settings and after doing that it seems to have improved mine. 78% after 1 hour 35 of usage since I took it off charge at 5 past 6 this morning.
