How to unlock the iPhone (3Gs)

On a recent India trip, wanted to use my iPhone 3Gs handset with my local india number. Tried ‘googling’ the usual unlocking methods but somehow could not get the steps right(Later realised that i needed to download the ipsw file). Eventually, I found a kind and helpful soul on Craiglist/Bangalore who sent me a simple step-by-step process to get the job done.

Apparently, there are a lot of hacks out there who charge money to unlock your iPhone. Sumeet Gandhi is not one of them. Infact, his motive is pretty simple. He wants to create an iPhone users community in Bangalore and by helping more people unlock their phones, the reasoning is that the community will increase. Pretty neat.

Outlined below is the process you need to follow if you need to unlock the iPhone 3Gs (basedband 15.04.02). All credits due to Sumeet and the respective sites from where some of the screenshots are taken.

And ofcourse to the Dev Team. They are the original rockstars

Note: Whatever you may do, DONT ever pay any of the sites which come up first on google search for the unlocking software. They will charge you a bunch of money and send you software which has been developed by the Dev Team and is freely available on the net. If you do feel a need to spend money, send it to some charity along with a postcard to the Dev Team as they don’t accept donations.

Electronic waste

Saw this old iMac in the trash room left by somebody who has no more use for it .

Wonder how will it be disposed off ?
Wonder if apple has a formal policy for reclycing stuff ?
Wonder if the user could have disposed it off in a more environment friendly manner ?
Wonder if it will end up in a developing country ?
Wonder if will even be useful in it’s current format in a developing country?
Wonder if I am wondering too much and ‘Waste Management’ will dispose it off appropriately ?

What would you have done ?
