Just jailbroke my iPhone 4 with pod2g's untether and everything seems to be fine, except everytime Cydia updates its packages, it gives me an error saying something like "POSIX: operation timed out" or "POSIX: connection refused". Also, whenever I add a new source, I get the same error message with a more obscure twist, like "POSIX: Hash sum mismatch" and "Fetch failure 010101asdasdlololsomething". What does adding a new source have to do with POSIX or other sources? And now it also began doing that with other sources too (Zotldtldl or whatever, Cydia/Telesphereo etc.) Does this just mean that the repos are down?
