When we first got wind that google was going to be rolling “cupcake” into the Android open source project, but noted that there may be a chance that T-Mobile G1 users may never see then on their handsets. It’s completely up to T-Mobile to decide what version of Android makes it onto the G1. However, Engadget got a note from HTC yesterday afternoon, stating that they were confident that the majority of the “cupcake” updates would make it to the G1. HTC made it clear that they have no control over the situation and that the decision is up to T-Mobile.
I would like to note that Google has a vested interest in making the G1 a successful phone. Adding stereo Bluetooth support, on screen keyboard, and other capabilities would only increase the G1’s marketability and in turn would boost Android’s reputation. We can’t say when or what will be included in T-Mobile’s next OTA (over the air) update for the G1, but I’d expect it to add a few more desperately needed features.
