The update will be available over the air as expected, if you are unaware about what Android 1.5 brings to the table then let me make the basic known. You get on-screen QWERTY keyboard, ability to record video, faster stronger better we browser, you'll be able to upload photos to Google Picasa online photo album, and finally, the ability to upload videos to Youtube.

I am very pleased with my over all g1 purchase. Google and Htc are committed toward creating the best handset. Now, with the new update, g1 users no longer have to suffer criticism over what g1 lacks compared to othe smart phones. Thanks, T-mobile.
