Hi
I have jailbreaked my iPad 3 for the very first time, with no problems. But I do have one question.
If I use iTunes to manage my iPad and want to make a backup via iTunes, will the stock rom be overwritten by the new jailbreaked iPad apps?
No, iTunes doesn't mess with the jail break tweaks from Cydia. All it does is back up the apps you buy from the App Store. To backup the Cydia tweaks, you have to get a backup tweak such as PKGBackup. So, you'll have two backups - one for stock apps and one for jail break tweaks...
About Cydia, is it possible in Cydia to remember my account so I don't have to login each time I want to buy apps?
Unfortunately, no, there isn't. It'll remember you only for that one session. Yeah, it's annoying, but that's the way saurik designed it.
Another ting, if I go in App store from iPad and want to see what I have purchased I can't login anymore, why or is that normally from now on, when iPads are jailbreaked?
Huh. Now this could be a potential problem, because being jail broken in no way messes with going to the App Store and looking at your purchased apps. Have you tried logging out and then back in to the App Store? As far as the App Store and iTunes are concerned, they should work just fine. They both just "ignore" the fact that you are jail broken and work as if you are stock. So, try to re-log in. Let us know if that problem gets fixed...?
Hope some of this reassures.
