I have an AT&T iPhone 3gs 4.3.5 - 05.16.02.

All I want to do is to be able to use my iPhone in Panama.

Is it possible to unlock the SIM so I can get a SIM from a local provider in Panama and use the iPhone for voice and email?

I can't get thru all the techno terms and jargon to understand if this is feasible and what my first step should be.

Can some please help this uninformed newbie and put the steps for me to follow in simple layman terms?

Any help would be most greatly appreciated.

thanks, Pat

You can unlock any 3gs via ipad baseband but you lose gps support, use redsn0w and ultrasnow from cydia and my question is

I just buy a gevey ultra iphone 4 unlock chip, also i buy micro sim adaptor.
I made a few modifications to the sim adaptor and combine the gevey with the adaptor and micro sim to fit 3gs 4.1 firmware 5.16.02 baseband and managed to fit it in pozition.
Next i got the message about the source cydia.furi.. Added it installed the mod and reboot the phone
So i accepted the popup from gevey,got the o signal bar but not the unlock..
My question would be now can the gevey ultra for iph4 unlock 3gs if positioned right?
I would like a sure answer, don't guess. Thanks

Edit : i read on another page that it can work
