I got this:

but it was so flimsy that I am taking it back, no way worth $30, it's more like a cheap silicone from ebay for $1.99.
I thought my old silicone cases for v1 would not fit, but when I got home from buying iphone and tried on my Paul Frank case from v1 it fit perfect. In fact almost all my old cases worked for v2 with exception of the fitted hard cases. I did order an Invisible Shield from Zigg.com.
