i am using iphone 3gs form past 5 days i bought a used one few days ago.
the firmware on the phone is 3.1.3(jailbroken) and i am thinking about upgrading because so many games and apps (like infinity blade) require higher firmware.
and i am also facing some mic issue sometime it doesn't work when i call someone they can't hear me but i can hear them i found that the people who bought iphone few days ago they also facing same problem.
i hope it's not because it's a used one. because i can't go to apple i have to do it myself or go to an expert.
so help me if any one knows about the mic issue.
and i want to know if i upgraded my 3gs (3.1.3) will i lost anything. and which jailbroken firmware is the best now.
will i able to use my SIM card i am using now. i live in india and i am using airtel(i know some of you didn't heard that name before).
so please reply.
