I use an iPhone 3GS with no phone service, for apps, email, web. I was thinking of upgrading to iPod Touch 5 to replace it, so I've been doing some research. It seems that iPod Touch 5 only has half the RAM of iPhone 5. I was wondering if, for this reason or any other reason, some apps do not support the iPod Touch? Does iPhone support equal iPod Touch support? Will I be left out with some apps only supporting the phone and not the ipod? I see a lot of apps on the app store that just say "This app is designed for both iPhone and iPad." Thanks. Hmm, did some further research and realized these two devices have totally different tech inside, I guess it's not fair to compare them in terms of performance but I'm mainly just concerned about app compatibility.
