After unveiling plans for PlayStation Mobile last summer, opening the storefront and letting its software development kit marinate in beta for roughly a year, Sony has finally given the dev platform the "go" (no, not that one) for launch. Developers eager to create games and apps for PlayStation-certified Android tablets and smartphones -- and even the PS Vita -- can download the SDK so long as they're willing to shell out $99 a year for the chance to publish as many titles as they wish. If you're ready to start slinging code, see the source links below to enroll in the program and download the SDK.
