Updated to beta 5 on my developer device (iphone 5), and I haven't been able to install or update any app. Anyone else seeing this.
Reset All Settings fixed it for me.
Then do a clean install. Reinstall iOS 6 and update to iOS 7 beta 5.
great, can't install any apps on my iPhone but works fine on my iPad
Reboot your phone a couple of times.
Known Issues
App downloads can get stuck in the "Waiting" state.
Workaround: Reboot your device once or twice to resolve the issue and allow subsequent downloads to continue.
What method/link?Keep in mind this is a known bug and Apple already knows about it. It's in their seed 5 release log.
If the reboot do not work, try my method (link is above)
