Short answer: I don't use iTunes, and I already said I'm for playlist functionality.
Long answer:
1. I use Ubuntu, therefore iTunes isn't an option. We are out of the stone age, so switching to a stone age operating system (windows) just to use a single piece of stone age malware (iTunes) in order to use my stone age phone (iPhone) isn't even an option on my radar. Yes, that makes me stubborn. Stubbornness is the cause of human progress. It was stubborn cavemen who didn't settle for not having fire. It was stubborn scientists who didn't settle for not having electricity and running water. People have always mocked the minority who demands progress, and yet it is the minority who has advanced civilization. People are mostly retarded barbarians who don't challenge mainstream ideas because they'd rather feel accepted. I don't care about being accepted by retarded barbarians, I care about human progress and quality of living, which means thinking outside the box, refusing to accept the status quo (which is really what jailbreaking is all about in the first place) and thus inviting enterprising entreprenuers to serve me (like the guy who made PwnTunes).
2. I listen to a lot of audiobooks, about philosophy and economics and politics and for some reason when I was dumb enough to bother with iTunes, when I changed my audiobook files from "music" or whatever to "audiobook" they would dissappear into oblivion on my phone and yet still take up space, and I would have to go through a HUGE hassle trying to find and remove each on individually only to re-add them as normal music files which mucked up a whole lot of stuff in the process.
3. I already said I'm all for playlists. I also need the functionality of choosing to play non-synced files from folders, which has been basic functionality on Android for years. Not that I'm an Android fanboy, but it completely blows iPhone out of the water in every respect. I switched to the iPhone 4s because I got it in the box for $100 and figured it would be an exciting new toy to hack. Instead, I'm learning that it's all about the money and that the entire purpose of jailbreaking is to make the phone as close as possible to an Android. Coming from Android, I can say that is an objective fact. All the most important and usually paid jailbreak apps and features for iPhone are standard and free on Android, which leads me to believe the goal of jailbreaking is to make the device more modern, to give it common sense functionality a la Android. $30 for MyWi? That **** is free on Android, there's at least 5 free apps for it. $6 for PwnTunes? Stock functionality on Android. Pay for BiteSMS??? It's literally like the beta version of the very first (free by the way) SMS apps for Android from years ago. Look at GoLauncher EX, look at GoSMS Pro (both free), look at PlayerPro, QuickPic, Vignette. That is how phones should work.
So iTunes isn't an option, and I need playlist functionality, which I had already mentioned so pardon me for being confused by your question. On the flipside, nobody has been able to recommend an app that fits my basic need. Is this because no such app exists for iPhone? In the meantime, I've "solved" the problem by paying for PwnTunes, which is a workaround at best.
