Hungry G1 users on T-Mobile can satiate their hunger with a cupcake, more precisely Cupcake 1.5. The update is now being sent out to G1’s for users to update. Custom ROMs, however, may not get the notification that an update is available and will have to be removed. Amongst the new features in 1.5 is an official on-screen keyboard. The download is OTA and comes in at around 44 Mb; it’s available to T-Mobile UK and U.S. customers. T-Mobile UK were kind enough to have released the news via their Twitter feed @Tmobile_UK.
