Multi-Tasking?

[Sim-X]

I feel like such a newb.... lol - coming from TP2 MightyRom which I customized top to bottom. I really miss my TP2 keyboard A LOT. However the phone is beautiful but this on-screen business is gonna take some getting use to.

Anyway so when you close an ap does it actually close down or stay open in the background? How exactly do you get multiple aps running if you wanna do a few things at once? I just don't know if the ap actually gets closed or not.

Also I can't figure out how to shut off vibrate on an incoming text which I am finding very annoying.
