Now, the first large corporation has entered the jailbreaking community.Toyota has released a theme under their Scion brand into Cydia under the ModMyi repository. The theme utilizes the full extent of the jailbreaking app Winterboard with custom icons, carrier logo, wallpapers, and sliders.
With an estimated number of 10-15 million users with a jailbroken iPod, iPhone, or iPad, other companies may submit themes into Cydia to advertise their product. This means that Apple may have to eventually recognize the significance of the open source iOS device. This also could mean that other companies that create products that are high in demand (like Adobe Flash) may come to Cydia to distribute their apps because Apple does not allow them into the App Store.
Either way, it seems like it is a win-win situation for the jailbreakers and the companies making themes. The future looks bright for all those who jailbreak.
