I got my iPhone 3GS last year for christmas, and at the time, I was using my mom's dell laptop. Over time the laptop crapped out, and no longer turns on. I went off to college this fall, and got a Macbook pro. Because the old laptop is broken, i've been unable to sync my iPhone to my new mac. I also want to add that my iPhone is jailbroken, and is running ios 4.3.1. What I want to do is to find a way to be able to use my iPhone with my mac, and also update it to the most recent ios. I don't care about losing jailbroken apps or tweaks, but more about keeping my photos, conversations, contacts, etc. Any help would be greatly appreciated!
