Well I might have made a big mistake today.I bought an iPhone today and the ad read"Brand New Apple iPhone 8GB - Unlocked".It looked brand new with the plastic still on the screen and in pristine condition.The guy said he only took it out of the box to jailbreak and unlock it.When I picked up the
phone it already had the installer app on the screen and the guy showed me YouTube was working and wifi worked with no problem.I told the guy I was already an AT&T customer and I asked him if I just put my sim card it it would it work right away.His answer was yes,just put my AT&T sim card in the iPhone and I would be ready to go.Well I get home and put in my sim card and what do you know,it says NO SERVICE !!
After checking things out I found out it was originally a 1.1.2 firmware phone that he jailbroke and downgraded to the 1.1.1 firmware.The Modem Firmware says 04.02.13_G.So my question is this,is there a way to use the phone to make and receive calls with my current AT&T sim card without somehow activating the phone on itunes??I don't care if it's unlocked for any sim,I just want to use my existing AT&T sim without activating through iTunes.
I searched the site and either I overlooked the answer I am looking for or I am just plain stupid.Sorry if I overlooked the answer.
Thanks in advance.
