Hi everyone
I am sorry if i ask something strange or stupid, i am new to iOS and have very less updated knowledge.
I recently bought an iPhone from a friend and it is locked. It is iPhone 4 with iOS 7.1 installed and base bank 4.12.09. It is unlocked and i am not sure that at which carrier it was before. I am not intending to IMEI unlock it or factory unlock. I just want to simple unlock it that i can use it in my country. I previously had 3G a long time ago and i knew that jail breaking and then installing Ultrasn0w is everything and it solves the purpose.
I searched on Google and found that 4.12.09 BB is locked. I had an alternate option in mind, either i upgrade it (this would change its BB) or downgrade it (i am not sure of change in BB) but then it would make it possible to unlock it.
Can anyone help me out solving this issue.
