CNET News Daily Podcast: Sprint's Virgin Mobile buy

Sprint on Tuesday announced it was planning to snatch up Virgin Mobile in the U.S. The buy puts Sprint in a good position to compete with prepaid offerings from other carriers. We talk to CNET News writer Maggie Reardon to hear what kind of money Sprint is making off customers of these prepaid programs, and what it's planning to do with Boost Mobile, the prepaid mobile phone service it already owns.

We also cover Tuesday's billion-dollar acquisition by IBM, and a new study that's found that text messaging while driving can take away enough concentration to drive the length of a football field without noticing.
