I was lucky enough to get the Costco bundle opening day, then ran to VZW for the otterbox case. I've reconsidered my position, and am planning to purchase the extended battery. What's the best case to purchase that's compatible with the extended battery? A link would be greatly appreciated. Also, will the phone work with any of the Costco extras with the extended battery? What about with the aforementioned extended case? Finally, is there a list of useful apps for the Bionic? Coming from the Eris, this phone is amazing and I feel like I'm totally under-utilizing it. Thanks all!
