At Friday's press conference, Steve mentioned that Apple would give all iPhone 4 buyers a free case/bumper to alleviate any signal issues. But he also mentioned that Apple can not meet the demand themselves, so customers will be able to choose from Apple's own bumpers, as well as third-party cases sourced from other vendors. SO, my question: Who are those third-party manufacturers, and what model(s) will they be offering? Any ideas??
