Is icade mobile good for me?

I have an IPhone 4S and I have an app called GBA4ios which allows me to play gba games. I was wondering if I used the icade mobile, would it work for my gameboy app? I don't want to get it if it won't work. If it doesn't, are there any iPhone gaming controllers that have all abxy buttons, a d-pad or analog stick, and bumper or trigger buttons that would work for my gba games?

IPhone 5, what size, 16 or 32GB?

I'm due for an upgrade tomorrow and my heart is set on the iPhone 5. Now I only have one problem. What size to get? It's between the 32 and 16… Now I'm 18 going to college in the fall and i take an average amount of pictures and have an ipod with all games and music on it. It is 32gb and i have about 14gb of music on it. I don't really want the games on my phone and if i do only a select few. So i would like to have all my music on one place but its such a large amount. Some won't be on it though becuse a friend let me sync my ipod with his library to get his bought music and i have yet to figure out how to get that on my itunes but nonetheless at least 10GB+ of music. I do want it all on one device but i could live with it on my ipod. I also don't know what the icloud is. Only that it helps with storage. If i could have a quick summary about that it would be greatly appreciated. Also if i do go with the 32GB phone… My parents would pay for it but I would have to put forth the extra hundred, which is very reasonable. So I don't know which size to get. 32GB or 16GB. Please any advice?

What Walkie Talkie Apps Are There?

So I like to ride my quad and dirtbike with my friend a lot, but communication is obviously hard to come by on those things so I wanted to come up with a way to wirelessly communicate. I was thinking, I have an iPhone and iPod touch 4g, so are there any apps that could use (not Wi-Fi) but either Bluetooth or wireless frequency that is like a walkie talkie where I could use the headphones with the microphone to communicate. If not, does anyone know of any devices or walkie talkies with headphones in which I could do the same thing, without pressing any buttons.

What can hurt your iPhone's performance?

My girlfriend insists that if you unplug your iPhone or MacBook while its still charging and not at 100% yet, that it will hurt your iPhone or MacBook. Is this true? What are some other things that can hurt the performance?
