What network do you use?

T-Mobile unfortunately. Likely will move either to Sprint or Verizon once my contract is up. Love my rooted MyTouch, but I need a new phone, and the EVO 4G is looking pretty attractive, although I'm going to wait until WP7S comes out to decide on which platform, and as a result which carrier, I will be going to.

Vodafone.

Orange

 T-Mobile

As I have an iPhone, AT&T, unfortunately :(
 
I used to have Verizon. It was fantastic.

I do not own a cell-phone.

AT&T is the best in our area. I love my iPhone.

Verizon

t-mobile

I'm on Alltel, but that got bought by Verizon... so I clicked Verizon.  It's not bad... I guess... It works, can't complain about what I use it for.

" Vodafone. "

I guess Verizon now since Alltel merged with them.

T-Mobile. It's the cheapest plan for my family and me.

Oops, forgot to make a post of my own. As for me, I use Sprint. Pretty good and cheap service, although sometimes I get text messages that were sent over an hour ago.
 
Oh, and can we move this to Off-Topic? Sorry about that.

Verizon.  My current phone has a pretty decent camera. 
 

AT&T because Iphones are awesome... 

Straight Talk.

Verizon

T-Mobile.

Phone? Bell I think.

I'm with Bell here in Canada, it's kind of expensive, but the best available option.

Verizon but I want AT&T because I want an iPhone but my parents pay for my phone as long as I stay on their plan which is on Verizon so if I switch I would have to pay for it myself.

The Cerberus one.
