I wouldn't hold my breath for a PSP release, as they are the same devs that made this in the first place that would probably do it so they would cripple it just like this version.
They probably could've made a PSP version to start with but went this way instead so there must be some reason why they didn't make a PSP version to start with.
Did they officially state WHY they crippled it? I don't care what it can be done through so long as I don't have to build something and eventually we do get a non-bastardized version. On an iPhone would be a pain in the butt for me though. I don't want to deal with any Apple products.
