1) You're absolutely correct, I don't have any ROMs to download for iOS, and as I said they're completely unnecessary for me. Why would I want to download any ROMs? I can completely customize my user interface and modify virtually every aspect of my phone just by having it jailbroken.
2) You're incorrect on this one. I would never want to decrease the clock speed of my CPU (it's not called upgrading/downgrading which would imply a hardware-related modifcation, it's called overlocking or increasing/decreasing clock speed) but if I wanted to overclock my iPhone I could, but I don't need to.
3) Wrong again. We call that *nix, using the wildcard as a replacement for 'U' or "Li" as would be done if you were using a regex. I've never seen anyone use the phrase "X system" because quite frankly it isn't very meaningful. And still, I have no need to create or increase swap space on my device with 16 GB internal memory. You'll notice if you go to apply at places like Facebook or Google they'll use the term "*nix" and not "X system."
4) 3rd party developers are what make up the official App Store and Cydia app store. This is part of the reason that the Apple App Store has almost twice as many apps available than Google Play's Android Market (as of 2/2012 the Apple App Store had 725,000+ apps, as of 4/2012 Android Market had 425,000+ apps). I even just downloaded an open-source app this morning straight off of Google Code (http://code.google.com/p/pirni-derv/
) through mobile Safari with the help of iFile, yet another 3rd party app.
It's clear that you're not very familiar with iOS or what it's capable of when jailbroken. I'm trying to share facts with you and get facts from you but you're just being a troll and spewing nonsense. iOS as a "superior OS" could do all the above and much, much more as well. I can run the Social Engineering Toolkit in a mobile terminal on my phone, SSH into any of my Linux-based machines and copy/transfer files, remotely track my phone and have it automatically or manually take pictures of someone that may have stolen my phone and even turn on the microphone so that I can hear what's going on at any given moment, etc.
