The cover on my Droid also was coming off very easily when I took it out of my pocket. I now have it taped on, but would rather have a correct cover. I put it on the wishlist.
just send motorola an email they will send you one free of charge
Motorola sent me an email saying that I need to obtain a warranty replacement for it. Is this what you did?
Also, the 3 free doors is now one for $4.99 (but was offered 25% off, so $3.74). Not cool.
