I only use those cases since they have the built in screen protector and I can't get an Epic Touch 4G unless one comes out
Based on the e-mails I've gotten back from a few manufactures, including Otterbox, they're just getting a feel for demand. So if there is any manufacture that doesn't have a product that you want, just e-mail them asking for it. If enough folks request it, they'll make it.
well, the good news is that Ballistic came out with a case for these phones today; its not their HC Series, which you can drop from a rooftop and not have a damaged phone, but, its now the most durable, protective case for these phones...
If you are concerned about damage to your phone cause you drop it a lot, or work in harsh environments, this is now the best protection you can get.
If a larger, bulky case bothers you, then stay away from this case..
