Video: Magento via iPhone
As mentioned earlier this week, a new iPhone optimized Magento theme will be available in the next few days via Magento Connect. Additionally, as part of the upcoming 1.1 release, automatic detection and delivery of packages, theme(s) (templates, skins, css, layouts) based on the user-agent (client) may be associated on a global, website and store view. The video below gives a preview of Magento on the iPhone.
Magento will thus be mobile ready for every out of the box implementation.
Note: As much as we love Magento, please do not attempt this at home ("[Man] surgically alters thumbs to better use iPhone")
