I'm thinking that root access might be handy for
<Dr. Evil pinky> Adding "127.0.0.1 admob.com" to the hosts file </Dr.Evil pinky>
I'm curious if that would block all that adware from spamming me when using the "free" software.
the only risk in this one, is not knowing what your doing. very simple method. download, rename, restart in recovery and install. nothing to it, and the only issues are with your battery dying, or you pulling the battery out. otherwise its foolproof. make sure you have the whole file. if your even slightly hesitant, dont do it.
I did the manual update to 2.0.1 and this appears basically the same so I know I can do it I just wonder if, a year from now, they will pull an "Apple" and spank anyone with the exploit.
From what I can tell these patches just have a script that mounts the /system file system and copies files to it. If the "recovery console" has root access wouldn't we be able to build your own zip files with (for example) an /etc/hosts file in it and just pretend its an update? This might give you temporary root access without a full fledged phone hack.
