Latest scoop for Android-fans is that T1-mobile is going to offer an over-the-air update for G1, the father of Android devices. What, how, when are still not out but the update atleast is confirmed
AndroidSPIN is backing up the credibility of this claim but offer no insight into the version of this update. It might be Android 2.0.1 most probably but can go no less than 2.0. OTA versions for both of these OS have been prepared.
Some people seriously doubt G1’s performance with Android 2.0.1. If it’s really as poor as they say, T1 may stick with 2.0. But anything newer is mostly better, so there’s a high probability to get 2.0.1.
