Last week, VizWiz stopped working for me. The app won't even open. I find it in my app list, double tap like I do all other apps, and it does not open. I've tried uninstalling and reinstalling the app, rebooting my phone (several times), and so far nothing has worked. I'm using an iPhone 4S. I've downloaded Omoby, but Omoby isn't nearly as powerful as VizWiz. Has anyone else hade this issue with VizWiz, and if so is there a fix? I've found it to be quite useful, and I'm hoping to be able to use it again at some point. Also, for what it's worth, I dropped an Email to the VizWiz developers documenting the issue.
