Unlocked 1.0.2 upgrade to 1.1.4
I bought an unlocked iPhone from America over 2 years ago with 1.0.2 firmware.
Not sure what method was used to unlock it but it was right at the start of the first launch of iPhone.
I am now tired of not being able to update the firmware and would like to give it a shot.
I have been researching on how to do this and found that due to it being unlocked with 1.0.2 I need to Virginize my iphone.
I have downloaded Ziphone 3.0.
Am I right to use Ziphone to erase 3.9 bootloader and then restore firmware to 1.1.4 by pressing "Prepare for upgrade" then go to iTunes press "shift" whilst clicking on restore and choose file for 1.1.4 firmware.
When restored go to Ziphone and press "Do it all" and it should be unlocked jailbreaked and upgraded 1.1.4 ?
Should I upgrade my iPhone this way or is there a simpler/better way of doing this?
I am very thankful for any help :o

I have researched how to upgrade my iPhone but not getting anywhere.
Is there any way for me to upgrade my iPhone or should I sell it and buy a new one?
