I was looking for a webcam widget in the Notification Center for Apple’s iOS for on my iPhone but that wasn’t easy untill now.
I’ve also mentioned a Google Android alternative.

The options that are out there are:

Apple iOS Notification Center Widgets:

– AlpenCams by Arrow Webprojects / Eric Horstmanshof | 0,99 dollar – still needs some tweaks, and lacks option to add your own webcam(s) but for snow webcams this is best option out there.

– Glimpse by Arno Appenzeller | 1,99 dollar

– Photo of the Day by Francis Bonnin | 0,99 dollar – This uses RSS feeds to get a webcam (a bit more difficult), build one here.

– LiveImageView by Bertrand Kerautret (not yet in the App Store, soon expected according to developer, only able to use via jailbreak for now)

Google Android Google Play background webcam image:
