i have a iphone 3G with serial 889059TXY7K, Model MB496B,Model Firmware 05.11.07 and 5.09 Bootloader. I am little puzzled abt Older Bootrom in an iphone 3g. Just check this link http://www.redmondpie.com/download-s...mware-9140380/
Here it says that snowbreeze 3.1.3 creates a custom 3.1.2 ipsw FW which can later be unlocked via ultrasn0w or Blacksn0w but only for OLDER BOOTROMS.
does the term older bootrom apply to 3GS only. what does this exactly mean and how can i check it on my 3G.
Don't go near sn0wbreeze, ih8sn0w .....
don't go near anything not made by Dev Team.
If you want custom firmware, use PwnageTool and run it on a Mac. Period !!.
The bootrom discussion is only relevant to the 3GS.
You have a 3G, you are fine.
Again, use pnwagetool to create custom fw. If you don't have a Mac, find someone who does and use it.
