im having the same problem...host unreachable, been trying for three days now still no luck ..everything went well when i jailbroke and unlock except for this...with cydia not working whats the use to jailbreak...cant download anything.. i miss cydia please help
Here,so many post about it.Cydia is not down for me on 2.2&2.2.1.Maybe it has some issues such as cache failure,host unreachable,unable to load. Then its reloading normally&everything is ok...
Hey there. Sorry to bring back a post from weeks ago but for the last two days when I attempt to load cydia I receive an error message unable to load (file doesnt exist)
The odd part is that I can install any app but I cannot see the preview of the application like I was able to in the past..
I have a problem similar to yours, can install and remove apps, but the preview is broken.
*Edit*
I found a way to fix this problem, simply use the terminal in iPhone or SSH to the phone and do apt-get remove cydia, then do apt-get install cydia. Preview works again.
