I'm happy to announce the official release of Popup Blocker via the ModMyI source. This extension helps to block many of the annoying alert popups that you see all the time on your iPhone/iPod. You can customize the configuration to block any of the supported popups either when your device is locked or unlocked, and can additionally say whether the device's screen should turn on when the alert occurs. Currently, the extension supports: Calendar Alerts SMS Alerts Voicemail Alerts Location Requests Accessory Warnings Network Lost Warnings App Deletion Warnings App Store Ratings Low Battery Warnings Low Disk Space Warnings Backgrounder Alerts Call Failure Warnings I plan to add more popups in future releases. This extension costs 99c USD (via PayPal) and is activated through the Settings application.
