One of my buddies had one of the "4g" Metro phones and it didn't seem that much faster. We both had our normal average signal, but when I did some browsing (web and market) it seemed it was struggling to load pages. I didn't do a speed test but it was a bit faster then my Optimus with 3g active...but not by much.
Overall I am happy with this phone. It has been good to me, I've dropped it many times with no wear marks, I am suprised it hasn't cracked! The price is good at only like $99 new (I got mine for $40 new though) and seems worth it. After the slight modification to the kernal to overclock it has been doing great. My girlfriends Metro Blackberry has changed from 1x to EV the other day, along with my sisters Banter Touch. I just hope Metro keeps updating their towers and improve their speeds just a bit more! I get the worst speed test results (I couldn't believe the 1000+kbps I see above!) but browsing is noticeably faster so I'm not pulling my hair out waiting for simple pages to load!
