Hi All,

I am in India and I have just bought an IPHONE 3g (8GB).

These are the other details:
Version = 4.0
Model = MB489B
Modem Firmware = 05.13.04


I am thinking to Factory-Reset it as I want to remove/uninstall applications which are not of my use. I saw in Cydia -> Manage -> Storage that 90% of my "System" space is utilized.

I DO NOT need to take the backup of it as of now as it is new to me.

After doing "Erase All Content and Settings", I believe my iPhone will go in DFU mode like shown here

I think the OS also gets deleted when we do this.

So, when I will restore it through iTunes which OS will it install. I currently have iOs 4.0. I want to install iOS 4.0.1

I have downloaded it from here

Please guide .

Best Regards,
Ankur
