I wanted to do a backup of apps and data prior to updating a rom and TIBU was not in my app drawer. I thought maybe it hadn't reinstalled, or I hadn't reinstalled it after the last ROM update. I went to the Market and it showed up in "My Apps" as installed, but the "open" button was greyed out. I uninstalled and then reinstalled. Notification bar says it installed successfully, but still isn't in my app drawer. I'm just kinda wondering if anyone knows what's up with that?
