How to fix some mysterious problems.

Brand new fw4.2.1 bb03.10.01 iPhone 4, trying to run GP on a corporate Intranet network behind firewall using a HTTP proxy. Tried almost everything, used Terminal to launch GP and run as root, monitored the logs and could find out that GP is stuck at step "Fetching Firmware/dfu/iBSS.n90ap.RELEASE.dfu...". After some specified timeout GP takes the iPhone 4 out of DFU and it reboots normally.

I suspect that GP could not successfully talk to the designated Apple server for some reason. I changed back my /etc/hosts file by commenting out the line directing to Cydia and reloaded the hosts file. I checked that is reachable in Network Utility by traceroute.

The phone has never been restored nor an SHSH fingerprint saved in Tiny Umbrella -- I actually tried it but was not successful.

Anybody with any sensible suggestion?

My guess would be your corporation is blocking certain filesharing/communication protocols on your computer to try to thwart attempts to secretly download/export data on certain devices. Your workstation's security is probably set high, and certain functions used by greenpois0n's desktop app will not be able to run. Don't do it from a corporate computer, or log in as a local administrator if you can.
