Phone carriers hate me.

I got a really good new job. My dream job. They provided me with a mac. I currently have a straight talk phone (dirt cheap). It's not required but it would make my life a whole lot easier to have an iphone so it can link to my computer.

Both mine and hubby's credit is awful.. contract carriers want massive downpayments that we just can't afford. I have a ton of defaulted loans I took out to help bury my mother that I just couldn't keep paying.

Anyone have any ideas? Anyone who does payment plans and works with bad credir, whether it's prepaid or not, I don't care. I just can't drop a lot of money all at once right now. Any advice is appreciated!
