I'm looking for a hard type case that will fit the Motorola Droid. A case that fits on a belt, so it cannot fall off the belt. A case strong enough to stand on, lay on, won't open up by accident so the phone won't get damaged. I work in construction and have to crawl in attics and under homes and need a case that will protect the phone if I have to crawl on my stomach. And the case/phone cannot come loose and fall off the belt or out of the case. Any suggestions?
