Hello everyone.

I'm sorry if this will sound like a noobish question. I have been reading the forums for a while now, but i have not been able to find a clear answer.

I have a 1.1.1 which i have unlocked, jailbroken and activated a year and a half ago, using a tutorial on this very site (using anysim).

My question is: How would i go about upgrading it to the latest version? What are the steps that i need to folow? (and how can i back up everything on the phone, so it's not lost in the process? sms, contacts, etc..)

Thank you, and sorry again if my question is ill-suited.
