    So, I ws reading chronicdev's Google Code and found how to preserve the baseband on an iPhone firmware update.

    If you mount the RESTORE ramdisk, and go to /usr/local/share/restore/ you will find something called options.plist.

    If you modify the "UpgradeBaseband" (no quotes) property on that list so that its value is 0 instead of whatever it is (probably 1), then it will preserve the baseband.

    So if someone gets the Decryption Key, then we can upgrade our iPhone 3G's! This is what Dev-Team is working on right now; maybe someone wants to help. The key to ramdisks needs to be found, though. That is the major roadblock.

    So, if this is restatement, then sorry for being a n00b, but I thought this would be nice to know.
