The PearPhone is not available for purchase in stores. The PearPhone is a fictitious phone created as a spin-off of the Apple iPhone for the television show iCarly on Nickelodeon.
The PearPhone is not a manufactured device, and there are no Pear branded products available for purchase. The creators and writers of iCarly came up with this spin-off of the Apple brand due to copyright and license agreements. They were not allowed to use the Apple name or the names of Apple products in the show. These devices are merely stage props, designed to give the characters on the show a meaningful and relatable way to communicate.
