Use iTunes! http://www.apple.com/iphone/softwareupdate/

i just want to ask... if i do like this.. then my data will remain safe ? i make it unlock from pakistan... and it will lock again any chance ????

it l be lock be careful its has a dangerous method do not apply it require expert who has upgrade ebefore

^no phone software/firmware requires any expert to do that. it just requires one's fear able attempt but only first time. it doesn't harm if you follow the instructions.


following is the link how apple describes it to you. they give you all the instructions and precautions to take before and during the upgrade process.
