Downgrading your iPhone 2.0+ to 1.1.4 firmware

Updated : v1.1
Some users have reported that after installing firmware 1.1.4, the phone doesnt detect the SIM. In this case, the baseband has to be reverted back to the old one. So you have to download one more software called KiPhone and 2 extra steps have been added to show how its done i.e Step 5 and Step 6.

You might be wondering, why I am writing a tutorial about Downgrading an iPhone’s firmware, well 3 days back I got an iPhone 2G from a friend. It was running v2.0 firmware. Since v2.0 firmware doesn`t support the good’ol Installer (Installer : An application used to download and install a wide variety of applications packages hosted online. Something similar to Itunes App Store except this is free . Ofcourse data transmission charges are applicable as per your network), I decided to downgrade the firmware to 1.1.4 since there are lots of applications available for download on 1.1.4.

Anyways I decided to run a check on google to find the perfect method to downgrade the firmware and what results were quite disappointing. There were millions of methods and barely any of them worked. (I tried quite a few) So this tutorial is for people like me who wasted hours trying to downgrade their iPhone firmwares but don`t have a clue on how to go about it.
