Hello guys, I was thinking about getting an old iPad model and jailbreak it to see how it all works and I was thinking about the iPad 1 model, as it's the cheapest and the one I've seen with larger storage for the price, but after reading a few posts here I think the hardware in that model is not upgradeable to the latest ipad OS, so I was wondering, which cheap model would you recommend that's upgreadable to one of the latest OS versions? And, once it's jailbroken, can you still use itunes to install some of the apps? or it's all, 100%, done with a different app store, because if that's the case, does this app store has all the official apps? Many thanks!!
