you wana watch this iclarified video posted today. once updated only 58% can be restored and the rest only on mac! be careful... again, people rushing in feet first... if geo or the dev team say "ITS SAFE TO UPGRADE" then dont do it! either wait til they give the ok and/or wait til the 4.0 jailbreak is released https://iclarified.com/entry/index.php?enid=8857

i have a question maybe one of the devs can answer about multitasking. say i want facebook to run in the background. is that even possible? or will it just not run in the background unless facebook develops the app in a way where it is obviously necessary? for example, i would like to be able to get chat notifications and for that to happen it would need to be open. at least with backgrounder i can CHOOSE which apps stay open..

If a dev added me in his account to beta test his apps back on 3.0 when it was in beta, does that mean my id is still on file so I can install 4.0 beta without being a dev?
