I had to upgrade the OS on shinigamigirl 's phone to support an application and her phone is jailbroken.
Now I have experiance doing this but it was a while since I've done this. But when I researched on how to update it I just got so much new information. A lot of things have changed. And there are about 6 different tools to achieve the same thing. All claiming to be the easiest way and to work. But when you read their forums you see a lot of people complaining that it didn't work and that they are stuck.
But after 2 hours of stressing I did manage to update it and it works better than before.
