I've just started using the gameboy4iphone app and I noticed that a few save files have built up, many which are now unnecessary. Is there a way of deleting these on the iPod or do I have to do it through the computer somehow (if so, how?)? Also, just while I'm here, I know you can reverse jailbreak, but if you do can Apple tell if it was ever JB'ed in the first place? For instance, say I reverse it and need to get it replaced while in warranty, can they tell if it's been jailbroken before? If they can, will they definitely check before sending you a new one, or only if it looks suspicious? Finally, if they can, are there any measures you can go to to prevent them from finding out?
