It is on the 3rd of October that mobile devices that are PlayStation-Certified will get a brand new online platform to download games and applications. With PlayStation Mobile, the idea of Sony is to release a platform in order to give mobile devices users a PlayStation-like experience. Therefore, a wide range of mobile devices will be supported, from smartphones to tablets, and moreover, PSM will be available on the PS Vita. Even though common on iOS or Android, the most interesting thing is that the games will work accross all supported platforms: so you can play on your Xperia Play while on the move, and play on your ASUS Tek tablet when back at home.
Prices will range from 2$ to 20$.
The supported mobile device brands are: Sony, HTC, ASUS Tek, WikiPad, Fujitsu, and Sharp and of course PlayStation Vita.
From the answers on the US PlayStation Blog, Sony should add trophies for its PlayStation Mobile games, like on its PlayStation gaming consoles, to gather more users.
From established game companies, small indie teams, and one-man developers can download the SDK (Software Development Kit, the tool to develop the games on the mobile platforms) for 99$/year: a bit cheaper than for Apple. These developers can already download the Beta version of the SDK in order to launch their games right on the 3rd of October.
