I've got an iPod Touch 1st generation 16gb and just wondered if there's any way to quicken it up? (Its a dog of a thing at the moment, as all 1st gen owners know). Mainly I want it to run COD Zombies and Gangstar more smoothly.
No, there's isn't a magic workaround for the fact that the device has a really ageing processor (412MHz arm v5 vs 800MHz arm v6) and a minimal amount of RAM.
If it's a big deal to you, just buy a new one. You could always try restoring, if you want a placebo effect.
