G1 owners? That Android has moved on? That no one loves you anymore? Well, take heart: T-Mobile isn't done updating you yet. The tiniest of updates is now in the process of rolling out to G1s across the land, featuring improved "call performance" without "any additional feature enhancements." In other words, this is a one-trick pony -- but probably a good one, and it's still better than a poke in the eye with a sharp stick. The update's already being rolled out, and all customers should have it by March 15.
