I just jailbroke (correct plural?) my iPhone, installed Cydia and refreshed the page. This is what it said:

Error: Refreshing Data

Failed to fetch http://apt.modmyi.com/dists/stable/m...rm/Packages.gz HTTP/1.1 416 Requested range not satisfiable

Some index files failed to download, they have been ignored, or old ones used instead.

What can I do (I am obviously a noob )?

Thanks for any help
