Fair and Flexible?

I got my Sprint bill for the past month and my jaw dropped.  Since I've been traveling, and roaming, and using a ton of minutes, and using the internet via phone-as-modem quite a bit, my bill is enormous.  I'm going to try to expense it and get reimbursed by my company, because over half of it is business related.  Furthermore, because I have it set up to automatically be paid out of my bank account, I'm kinda broke until I get reimbursed.
