A lot of friends was asking me why I am not going out today because this is Saturday and now this is the reason, I am upgrading the IPSW of my iPhone. I purposely plan the whole day for it and I really used up the day before I went out for dinner.
Not to scare you guys, I took such a long time in updating it because I was trying to jailbreak it and there are lots of technical and complicated steps involved. At the end, luck wasn’t with me, I couldn’t jailbreak it. Anyway, I am still happy and enjoying the original IPSW verison 4.0.
By the way, IPSW means iPhone Software, it is the OS (operating system) of the device.
