The Register has posted a rumor, based on reports from mobile operators that Apple is already working on a slide-out keyboard version of the iPhone for corporate customers. If Apple releases this version it will be next year and won’t be aimed at the consumer market. According to the Register actual prototypes have been sent to senior executives at some operators. The new silde-out keyboard has some issues, which are not yet resolved and it will take more the 6 months to ship the final product to the market. Apple has started the work on iPhone with keyboard because it is one of the biggest demands by corporate customers.
