After being iPhoneless for a while (my 2G having been "donated" to the next passenger to use my cab that morning), I finally picked up a new 3G (2.2.1 w/ 2.30 baseband) this weekend.

After jailbreaking and installing and updating Cydia, I'm having a ton of problems getting it to connect to repositories.

Specifically, after updating the app, I'm not trying to update the sources, and a flurry of "host unreachable" and "cached failed" messages pop up, with bigboss, saurik, and zodttd URLs shown.

Network usage otherwise is perfect, over Wifi and EDGE.

Anyone else having problems, or have a clue what mine could be? It's obviously not any particular server, so I'm guessing it's client-side.
