[/EDIT]

i can confirm, it's the truth

Is this a pre-patch so we can install it then upgrade the iphone using iTunes?

No, the install.sh -script downloads all data from apple's website.

Is this for MAC or PC?

this isnt for ipod touch right? cuz everyone over at ipodtouchfans.com is all happy.

no you install the files to your phone and the run the script. you should have iphone connected to power and have wifi. because update will be done by the iphone not itunes

the readme says itouch/iphone

Apple's server is quite busy, only 200kt/s

OS - Doesn't matter
Runs on both itouch and iphone
Must be on 1.1.2 jailbroken
