Well, it looks like T-Mobile delivered on its promise of releasing an OTA(Over-The-Air) update for G1 users by their self-imposed deadline of March 15th.  Even though this update only brings forth an improvement in call quality, it’s nice to see that is was able without issue; unlike the experience Motorola Cliq and Droid Eris users suffered. If you haven’t seen the update yet, you should be seeing it very soon. So, the next question is will the G1 get another update?  Android 2.1, here we come? Time will tell, but we hope so!
