If you are signing up for a new account or a new line added to your account you should try

this is a dealer on ebay called telecomzone. when you go to their site just scroll down to the phone you want for the details. I got a brand new mogul from them last month for $100. I had to sign up for a new line. There is a 800 number to call to get pre-approved before you pay for or order anything. They said that you need to have no deposit required and no spending limit for your account in order to qualify. I spoke to Jane. She was very helpful. The only catch is that you have to keep the number with the phone for the first month - no esn swap if you are doing like i did. I used the new line added to my existing account to get a line for my daughter, but wanted the mogul for myself. So I had to wait until this month to do the esn swap for the mogul to my phone number, and swapped her new number to an older phone.
