EDIT: It's back up. Disregard. None of modmyi's apps are coming up, and when I try to readd the repository, I get two error messages. First: http://apt.modmyi.com Cached Failure OKAY Second: Error: Refreshing Data GPG error: http://iphone.hackndev.org hnd Release: The following signatures were invalid: KEYEXPIRED 1249480525 KEYEXPIRED 1249480525 KEYEXPIRED 1249480525 Failed to fetch http://apt.modmyi.com/dists/stable /main/binary-iphoneos- arm/Packages.gz Cached Failure Some index files failed to download, they have been ignored, or old ones have been used instead. OKAY Also, Down For Everyone or Just Me reports that modmyi is down. EDIT: Or it did, anyway. Disregard this message, it's back up. Moral of the story: Cached failure means the repo is down, but it will be back up.
