"Adobe® Photoshop.com Mobile is the easiest way to upload, view, and share your photos online from your phone. All you need is a supported Windows Mobile phone and your Photoshop.com account ID. Photoshop.com Mobile beta will be available as a free download in September."
Adobe claims that Photoshop.com Mobile will only support the MOTO Q, Blackjack, and Treo 700/750 series, although we're willing to bet most other Windows Mobile devices will handle it just fine as long as Flash is installed. At any rate, we'll let you know the moment it's available.
