Will be mobile(Android\IOS\WindowsPhone) applications? If so, when? And mobile devices can be part of the p2p network?
That is something in the future we will think about for our roadmap. The first form of this will be a client across mobile, web, and desktop, but the desktop will be most likely the version which participates in the P2P network in the form of seeding, hosting etc..
at the moment for you the main priority is exactly the wallet for the mobile environment? what about the development of the main code and explorer?
