How to unlock iPhone 4 from AT&T to T-Mobile?

Today I purchased a iPhone 4 off of craigslist. Its original carrier is AT&T, but i want to use it for T-Mobile. When i purchased it, the guy and i went to the AT&T device unlock request page and typed in all the info. After that it sent an email to him and said that the request was sent and that it would take around 48 hours to work. When i put my T-Mobile SIM card in the iPhone, It said "the SIM card you currently have installed in this phone is from a carrier that is not supported under the activation policy that is currently assigned by the activation server. Please insert another SIM card or request that this iPhone be unlocked by your carrier." Do i just have to wait and keep trying until the request goes through? Will the request even work? I have no idea on what I'm doing.

Can iPhone 4S take pictures on a timer?

So my friend has this phone (not and apple phone) and he has set it up so he can turn on his camera, set his phone down aiming it towards a group of people, and say a code word (he set his as whiskey) and it will snap a picture.

Can an iPhone 4S do anything like that? Or even a timer or something? If so, how?

How to unlock iPhone 4s carrier?

I got a free iPhone from my brother. Unfortunately it's on a Rogers carrier, while I'm on Bell. Bell Mobility gave me the number to a local cell phone shop, and they said, to unlock an iPhone 4s, it will cost me $120, which I find ridiculous. I searched Craigslist, and the price was $105.

Right now I'm using an old 'loaner' phone, because my original phone broke, and I want to use this iPhone to text and such. Bell Mobility said they can't do anything about it (they won't fix my phone because I was 7 days out of warranty).

Because the phone wasn't mine, is has a different phone number (and a different area code), but I'm sure if Bell gave me a SIM card, or something, they could transfer my number to the iPhone.

I've heard of 'jailbreaking', but I don't quite understand it. Some websites say I need to research a bunch of the carrier company policies, and some say Apple has restricted the use of a jailbreak.

Is there a cheaper way to unlock the phone off of Roger's, and on to Bell, or do I have to pay the $120?

Iphone display screen screwed up?

My iphone screen always flickers randomly sometimes it works sometimes it just totally flickers and goes black and i can't use it I don't understand why, it should work or it shouldn't work. Any help? Should i open it up and is there an easy fix or should i just get a new one through apple care which will cost only $49.

Bought unlocked Iphone 5 from CL, 5 months later phone is blocked?

I bought an unlocked Iphone 5 from someone off of craig's list roughly 5 months ago and I found out today that the phone has been blocked by T-mobile and I'm unable to make any calls because apparently the person who I bought the phone off of did not fulfill his contract obligations. I paid $420 for the phone and now I have a very expensive ipod and I'm pretty devastated. I'd like to know whether the Iphone still has value or if i should try and sell it internationally? Or if there's a way to use it for AT&T since T-mobile applied the IMEI block? Any help would be appreciated.
