Well, seems like Google wasn't lying when they said they would continue to work on providing carrier billing as a payment option in the Android Market, announcing the addition of the feature to Sprint handsets, alongside T-Mobile and AT&T. With three out of four major US carriers down, will carrier billing be coming to Verizon any time soon?
The feature has long been the request of many customers across all carriers, particularly internationally. This is largely due to the fact that Google Checkout remains unavailable as a payment option in a number of major international markets in South America and Asia, where Android's popularity is rapidly growing.
In the US, for those without credit cards, carrier billing is really the only convenient option for purchasing apps short of a rechargeable Visa debit card. Just how many people fall into this category, it's hard to say.
There is one other demographic carrier billing appeals to, though: kids. Parents with younger children who have Android smartphones can now look forward to all sorts of fun charges on their monthly bill. Of course, that also means there's a larger pool of impulsive app buyers for developers, and Google, to profit from - so everybody mostly wins.
Sprint customers, has the carrier billing option showed up in the Market on your Android device? Let us know in the comments.
