The Google Android Developers Blog has just announced that Sprint customers can now charge all their Android apps purchases from the Android Market to their monthly billing. This same billing option was earlier activated for T-Mobile and AT&T users as well as in other countries, particularly SoftBank, KDDI and NTT Docomo in Japan. For Sprint, the new carrier billing option for purchase Android apps will be gradually rolled. If you can’t see it right now as an option when you purchase Android apps, don’t lose hope immediately since it might appear in the coming days. If you’re one of those Sprint customers who were able to get the new billing option on your Android phone’s Android Market app, you can now start charging your Android apps purchases to your data plan. All charges will be added to your monthly bills from Sprint. So, now at least you’re assured that your credit card or paypal accounts will be safe from prospective hackers. Plus, charging your Android apps purchases will be easier now with the carrier billing option enabled. Google also announced that the direct to carrier billing option for the Android Market will be rolled out in other markets soon. Google is currently in talks with international mobile carriers to have the same option in their respective markets.
