Does Tmobile have home internet? Or info about other carriers?

I don't currently have internet, except for 3G on my tmobile iphone. I'm looking for internet so I can use my laptop for college, and was hoping tmobile might offer it, or even better have a bundle for home internet and cellphone that might lower both bills. I have an extremely tight budget at currently pay $50 for my cell. I don't think I could afford much more than $20 a month for internet. Also, I'm not sure what may happen in the future, so I don't think I could do a 24 month agreement or anything like that. 12 months would probably be ideal, if necessary 18 would be grudgingly accepted. If it needs to be 24, I can do it but as I said, who knows what may happen in 2 years. I hate the idea of paying a ridiculously expensive cancelation fee.

Also, if tmobile doesn't offer anything remotely similar to this, do you know of any carriers that will?

Also, I know that sometimes you have to pay to the router itself, not just the monthly "rent". If any of the carriers have a charge like this, please let me know as that might be a huge turn off for me depending on the number.

I'm a T-Mobile customer. I have been for over a decade and must say that their customer service can't be beat! I highly recommend them. Their new business model is contract free, so that is a plus for you (I'm still completing a contract, but even when it is up I will not be going anywhere).

I'm also a college student myself and a homeschooling parent of four, so internet access is a necessity. We have access through T-Mobile. Until February, we had a mobile hotspot from T-Mobile and used that to connect. In February, I got an iPHone that can do the same thing so I use that instead. I pay extra for the line my iPhone is on to have unlimited high speed data.
