Yesterday, Chris Leydon, who develops , a screenshot- and photo-sharing service, announced that he was on an update to the iOS app that already exists in the App Store because of Apple's new subscription rules.

Today, he backed away from that position, instead on an unconfirmed e-mail attributed to Apple CEO Steve Jobs, who allegedly said that the new subscription rules applied only to apps that delivered content, not "software-as-a-service," or SaaS apps.

"I know, it's a bit dodgy," Leydon said in an interview Tuesday, referring to the purported message from Jobs. first reported on the Jobs message.

According to Leydon's Sunday blog, TinyGrab on iOS would run afoul of Apple's new restrictions that require developers to add in-app subscription payment because it currently sells premium subscriptions that unlock features and provide users more storage for their images.

TinyGrab on the iPhone does that now with an outside-the-app payment system that relies on PayPal. The app itself is free, but an annual premium subscription is 10 ($16.22).
