Why did the space on my iphone randomly free up?

So not long ago, i had like 6.3 gb used up (i have an 8 gb, and it sucks balls, cuz i can't have *** on my phone) and now, randomly, without deleting anything, it went down to 5.7? I did nothing to it, it just randomly did this. Is theree any reason this could have happened? I just wanna know cuz i'm afraid my phone might be deleting things by itself but i didn't notice anything gone… So has this happened to anyone else?

Two devices with the same Apple ID?

Okay, so my dad FINALLY gave me a ipod, since i'm to 'young' to have a phone.
He owns a iPhone and i have the newest version of the iPod Touch. We use the same account and i wanted to know if the apps i download will download to his phone. And if i start using facetime and iMessage, if its going to send it to his phone as well? I added another email address (MINE) for the iMessage and Facetime, would that change anything?

Problems with iPhone not being recognized on iTunes?

My iTunes stopped recognizing both my iPod touch and my iPhone, and I have done everything that I have seen online to do (uninstall and reinstall iTunes, uninstall and reinstall device drivers, change usb ports, change iPod cables, etc.) and my iTunes STILL won't recognize my iPhone.
