Searching these forums I think I'm comfortable with the procedures involved in jail breaking my phone for the first time. However, I haven't been able to find clear answers for quite a few questions I have: First, I have an iPhone 4 running 4.1. I have a legitimate contract through AT&T with my grandfathered in unlimited data plan that I don't want to lose. Really at the moment I'm not looking for much more than some lock screen widgets, easier settings toggles, and turning my phone into a mobile hotspot for my wifi only iPad. Maybe a better notification system if there's a way to fix that too. Here are some of my questions: 1) I have tons of apps through the app store. I like finding new apps within the app store and don't mind paying for them so that developers continue to innovate for iOS. There is lots of info and customized settings in my apps. Is there a way to preserve those settings/data before I jailbreak? Also, it's my understanding that once jail broken I'll continue to be able to search and purchase from the app store as well as Cydia, correct? 2) I sync both mine and my wife's iPhones to the same iTunes. I assume there is no issue with having her phone run unjail broken and mine being jail broken. 3) Once 4.2 comes out and the subsequent jailbreak surfaces. Is there a way to preserve my jail broken apps before updating? I think this may be the tiny umbrella application tossed around in this forum, but I'm uncertain of how it works (what are blobs, etc?) 4) I know at any point I can restore to a previous unbroken state. If I do so I lose all my app data, correct? How do I go about updating to an unbroken state? And when 4.2 comes out will iTunes still alert me that there is a new update to the software if my phone is jail broken? What's the correct procedure for updating to the newest apple software? Do I have to downgrade to the previous apple software before updating to the newest? As you can see I'm very confused by all this. Like I said, I can wrap my brain around the actual act of jail breaking my phone. But I'm concerned with the steps I need to do to before and after jail breaking to preserve my data and not bork my data or my phone. I do take my idevice into apple whenever anything goes wrong so I'd like to be able to easily restore apples software so the warranty isn't voided whilst not risking losing data anytime I do it.
