According to Dominic, a T-Mobile Forum Moderator, the German company will start handling Market billing for its customers. <blockquote>Beginning on December 9th T-Mobile Android device customers will begin to receive an update to the Android Market application to allow for purchases to be charged to their T-Mobile account.</blockquote> They go on to claim the new system they will implement will save customers time. According to the post these are the highlights: <blockquote> * The Market application update will be invisible to you. No steps are necessary to receive the update! * To ensure that the update is received by all users T-Mobile and Google will stagger the update. You should expect to have the Market update by 12/30/2009. * Once you receive the update you will be able to purchase paid applications using your credit card or your T-Mobile account. * Reminder: Any applications uninstalled within 24 hours will NOT be charged to your T-Mobile account or credit card.</blockquote> I wonder if T-Mobile will charge tax on programs bought through the Market? There will also be a 24 hour refund period if the app. is not to your liking.
