How to transfer my old number to my new sim?

I had a standard SIM card, but got a microsim for my iPhone 4S, so how do I transfer all my data off one sim to another one, so my micro sim will have my old number instead of the one already on the sim.

Added (1). I gotta be possible because I did it once before but I can't remember how, plus my sister transferred her number from a standard sim to a micro sim then to a nano sim.

How do people learn to fix Apple products?

I'm really interested in flipping phones or iPods on Craigslist or eBay, but my question is (and I searched for the answer but couldn't find something to completely answer it), how do people learn to fix these handsets?

I could go online and find one for sale that says "Broken iPhone 4; screen cracked and won't turn on". The screen replacement is one thing, but how do people know what's making it unable to power on?

I guess my biggest question is where can I get more information on learning this stuff, and how the hardware in these devices work so I can start making a little extra money repairing them and reselling them.

My iPhone got wet and now the phone won't turn off. What to do

Also, there's a LED white light that won't turn off either. The fact that everything else is working is amazing me. I got out of my truck at school and, without me knowing, it fell into a puddle. When I got home I thought I left it at a friends so I went to his house and realized that I probably dropped it. I started driving around the parking lot and finally found it but not before I ran over it! The Otter Box that covered it not only saved it from my truck but also kept it visibly dry. I immediately dried the little water I found and I blew dried it. I made a 15 minute trip to get some rice and now it's in the rice and enclosed in a bag. The phone workes perfectly fine except for the LED light staying on, the phone not turning off, and the volume buttons not always working. Any suggestions on what to further do?
