cheap cell phone plans

I need to buy a new cell phone with service plan. Where can I find the best deals?

What web site has the best cell phone deals with plan?

I have two kids starting two different schools in a major city and I want cell phones for their safety and ability to communicate with me at any time. I have one through my job so I have nothing to do with billing, service or plans, and I have no idea which is best. I’ve heard one specific co. dumped customers for complaining, and some have poor service..Help! Which is the best??

What do you think is the best cell phone plan out there today. My plan ends in September and i want to know what plan i should go to. And what phone is going to be the best for that plan.
