He says "Here at my home office, I’m on the fringe of T-Mobile’s 3G coverage area. Yet, when I test the exact same SIM card here in the old G1 handset, I get full 3G speeds. With the Nexus One, I’m stuck on lowly EDGE service, even though I have the same four bars and signal strength. Clearly, there’s a software issue that’s causing the Nexus One to not “see” the 3G network.
I just did some quick poking around on the handset and made one very small manual adjustment. Guess what — I now have full 3G speeds at this location on my Nexus One!"
