I just got an iPhone 4 off ebay and it is on iOS 5 with baseband preserved to 1.59.00. From what i know, this baseband on iPhone 4 is software unlockable. Can anyone guide me as to how should i proceed with unlocking and jailbreaking of the iPhone 4 ? Also what should be done first - Jailbreaking or Unlocking ?? Requesting for some noob friendly links to tutorials (step by step) for the same and anything else i need to be aware about so that i do not goofup anything. I am bit scared about all this because this is my first stint with iPhone and i have never done all this. Please bear with me as this is my first post in this forum.
