I want to get an iPod. Right now, I'm looking at a 4th or 5th gen Classic or a Mini. I definitely want to increase storage and get a new battery. I've heard iPod Minis may be easier to mod since they don't need an extra adapter or something. But I've also heard some adapters like iFlash may not work on the mini. In your experience, what's the easiest one to work with? iFlash is supposedly the best adapter, but I'd rather not spend $40 on that part alone. Is there another adapter that would work reliably with 128 or 256 GB SD cards? I'm having a hard time finding a step-by-step tutorial for doing this. iFixit does have a good tutorial for taking it apart but I'd like more specific instructions for putting the new SD card in. I'd appreciate any advice you guys have to offer. Thanks!
