I'm a long time android user who was given a used ipad for free recently. Anyways I know that android programs are referred to as apk's. I'm curious what term is used for ios program's. Also I'm on system firmware 8.4.1. From what I've read this firmware isn't capable of being jailbroken yet. Is this true? And if not could someone provide me a link, either on here or via PM, stating how to jailbreak firmware 8.4.1. Thanks.
