Siri isn't working on my iPhone 4s

When I go to talk to Siri on my 4s, she says "Sorry, I'm not able to help you right now, try again later". I tried to work her about 2 weeks ago as well and it said this still. Now, 14 or so days later she isn't responding with anything besides this. Did I do something wrong? Has anybody else had this problem, please help!

Renting movie fom iTunes won't work?

I'm using my iPhone to try and rent a movie from iTunes, using my dad's credit card.
Everytime I press "Rent movie" the green box goes bak to gray an says "Rent $4.99"
I've done this twice and it hasn't started downloading OR asked if I want the purchase on the credit card. I'm worried because I don't want to end up renting the movie more than once, or something.
This is my first time renting a movie and probably my last.

Any tips on how to get the movie to download?
I'm from Canada, if that means anything, at all.

If anyone knows what to do it would be all appreciated if you shared it with me- thank you!

I can't seem to get my iPhone 3G to unlock?

I have an iPhone 3G that I have jailbroken and installed the iPad baseband (6.15.00) using redsn0w 0.9.6b6. I have installed ultrasn0w. Allowed the phone to respring. It will not locate my T-Mobile service. I have rejailbroken it twice both times reinstalling the iPad baseband. I have tested the sim card in other unlocked iPhone 3Gs and it works perfectly. It starts out with 1 bar of service, then goes to searching, then says no service. Please any help would be greatly appreciated!

How to remotely turn on and off Wi-Fi at home from another location?

I'd like to be able to turn Wi-Fi either on or off at home via iPhone App or some other method at work. When my kids finish homework, I'll turn on the Wi-Fi. Until then, it remains off.

My only thought is to use a IP controlled switch to physically cut the power to a Wi-Fi router.

Any suggestions on how I may be able to control the router remotely?
