Will the iPhone 5 work on T-Mobile?

I plan to buy the iPhone 5 factory unlocked when it comes out this September. I was wondering if I would be able to use 3G/4G on T-Mobile with it? I understand it will have AWS support but I want to be sure.

Why can't my laptop find my network?

I can't connect to the internet on my laptop, it says the connection "isn't found." I've tried unplugging my router, restarting the laptop, making a new connection, everything. Also, I use the Wi-Fi on my iphone and it works just fine on that. It stopped working all of a sudden yesterday and it's still not working. It's an acer laptop with windows vista and a cisco router, if that has anything to do with the problem.

It my baby boy advanced for his age?

I would like a child development expert to respond to my question. I have a baby boy who is 10 months old now. I think he is advanced and his behavior has me intrigued. Some examples of his behavior are: he likes to play the piano and drum, he is always making sounds or noises with his mouth or toys all the time, he looks concentrated when listening to music, he is moving his arms as if he's dancing without any reason, if he wants something he will pursue it relentlessly, he is having a tantrum just for few seconds if he can't touch my Ipad/Iphone or TV control, he is throwing toys on the table/floor just to watch how they fall and sound, and he will bother us until we share our food with him. I can see he has determination and character already. He is not sleeping well recently and I don't know the cause. It looks like he doesn't want to be alone. Also, he started to walk with no help but he can walk only 6 steps. He wants to climb on everything and can climb a flight of stairs. He is throwing his toys only to chase after them. He was trying to open our front door too. Are these signs that our boy is advanced?

Router keeps dropping internet?

Ok well its kind of weird so i don't know how i can fix this

Cox says that the internet power is good on their end with the modem so its obviously not that and has to be the router (belkin G series), but i have a lot of apple products and ill explain what's going on,

Apple TV connects to internet (Netflix, movie rentals, iTunes match) but not to computer for iTunes Home sharing with computer,

iPhone 4S connects just fine

iPhone 3G says is connected in settings but isn't actually using the Wi-Fi of router (Still uses 3G connection)
macbook pro when first opened connects and works and then after about 15 seconds drops the signal and then takes about 1 min and then connects automatically again.

iPad doesn't connect unless i do a power cycle on the router and then will be fine the rest of the day but if i leave and then come back home it won't reconnect until i power cycle again.

neither iPad nor iPhone 4S connect to iTunes for wireless syncing (feature of iOS 5)

PC Desktop will connect to router, but have no internet access till power cycle

all devices can connect to router just fine but with the lack of internet until after a power cycle

some days i need to power cycle a few times a day

How to fix nicks/chips in my IPhone?

I'm usually very careful with my phone but I bent down and my iphone slipped out of my purse onto the ground. I had a case on it but the volume buttons were exposed and I got 2 small chips on the side. They don't make the phone stop working or malfunction (they are just annoying and make my phone look bad) so I don't think the apple store would help or fix it. Is there any product that could fill it in? Do you think the apple store would fix it?

I have a white IPhone 4s.
