If you're a Verizon Wireless customer, you might be seeing a new payment option in your Play Store billing screen this morning. That option, as you've probably guessed, is carrier billing. We reported on the announcement just a couple of weeks ago.
For a lot of folks, this is easier than adding a credit card to the Play Store, but if you've got kids (or other spendthrift loved ones), this presents a new and exciting danger to your wallet. Be sure to set a Play Store PIN on your phone in the Settings menu - nobody wants to see a $40 payment to Zynga tacked onto their phone bill at the end of the month.
