LFS on an iOS device. whahahahahahahaha whahahahahahahah
I used a friends iMeh the other day and ridge racer was near impossible, LFS would be just dumb.
Also going iOS means a port into whatever shite language apple forces you into to stop porting to other devices, the risk they will pull your app at any moment and the fact they will demand 30% of your income, your first born and a kidney.
Is the OP serious or just a troll?
