I bought a 3300 Seidio extended battery when they were announced a while back and the back cover that comes with it is very poorly made. It didn't help that I dropped my phone a few times either.... Now the cover barely stays on. I'd like to get a new cover, but preferably not a Seidio one. I e-mailed about getting a replacement, and they said it would cost me $14.99. That seems a bit excessive for a poorly made back cover. Does anyone have a suggestion for another cover that will fit over the 3300 Seidio battery? Thanks!
