T-Mobile’s US offers to its Android phone users since late Wednesday that it has started updating Android Market to support carrier billing. The change lets users skip the usual Google Checkout process and instead pay for any purchased apps through their regular phone bill.
As the update is considered “invisible,” T-Mobile customers will not receive any notifications of a pending software update. Rather, you can access the new billing option by logging into the Android Market and making a purchase.
This update will roll out over the course of the next few weeks and should hit all handsets by the end of the year. Similar to Google Checkout, applications uninstalled within the first 24 hours after purchase will not show up on your T-Mobile bill.
The change will be pushed to the Cliq, myTouch 3G and other devices over the next three weeks and should be reflected in every T-Mobile Android phone by December 30th.
