Block Iphone 4 16GB from updating firmware

[Johnnybravo1]

Hey guys,
I will jailbreak my Iphone 4 16GB, firmware 4.2.1.
After that I need to prevent the device from automatically updating so I will not erase my jailbreak.
Do you have any suggestions?

Just select the option to not update when you connect it to iTunes.

Disable auto-sync and iTunes will always prompt you to download/install updates anyway.

I thought it would be much more than tapping out those buttons. Great to know it is that easy.
