Also on August 24, 2007, Engadget reported, by way of photos and a video clip, that they were called by the "iPhoneSimFree" team, who offered to show Engadget a demonstration of unlocking iPhone using a software-only method. Unlike Hotz's hardware hack, the code in this hack was not made available to the general public. Sales of the unlock started on September 10. These sales occurred through several resellers who were able to order "keys" from iPhoneSimFree, then pass the "keys" to customers, allowing the customers to use the software. On September 11, after one day of sales, the iPhone Dev Team announced that they had created a working "software unlock", and released it to the public for free. Utilizing requires some technical knowledge, although a simpler, GUI-based version was under construction. AnySim and iUnlock Reloaded, two free, GUI-based unlocking programs, have since been made available.
