Thanks to a trust source over on the forum, those of you who are still waiting for the Cupcake update, can get a slightly better idea of at least the latest timeframe you might be receiving the update. While there are still 11 days before Google promises 100% of all G1 users will receive the update, take comfort in the fact that you at least have a solid idea of when your update might arrive, rather than just waiting for that message to appear. Of course, that might not be any comfort at all. We should preface by saying while this list is purported to come from T-mobile internal systems, its unconfirmed!
