Unless there is really something special with IOS 7, I think many will keep the jailbreak over running betas.
I used to be that way when I used android but on IOS I'm not that way. Especially when the look and feel does not change with updates, that was pretty much the only reason I wanted to have the latest and greatest was for the different look and feel.if jailbreaks were more consistent i might change my philosophy about my need to remain jailbroken. for all we know it could be late 2013 or early 2014 before an iOS 7.x.x jailbreak will even seen
i like using new firmware when it is available, not waiting and watching everyone else enjoying it
