So I've been trolling these boards for a while now, gleaned some extremely useful information. but now I've run across a problem that, as a newbie iPhone user Need some clairifaction on. I Jailbroke my phone last week, and I've played around with a ton of different apps from Cydia. Winterboard causes issues, sbssettings is sweeet, SpringJump locked my device. but I wanted to send MMS messages. so I installed activatemms3g. And it did the eternal apple logo loop, I let it sit for about 3 hours to make sure I wasn't being impatient, but as it turns out I'll need to do a DFU restore. I found a website of how to do this, and installing iTunes on my PC at work is no problem, my concern is if I restore it here at work. When my main back up is at home. Will I risk losing my contacts? My pictures I already have and is no big deal, but I do not think I have an updated copy of my contacts at my office.
