5.63Mb/s and 0.55Mb/s up on my fresh-off-the-press T-Mobile myTouch 4g

FYI. I just got the phone this evening in Chicago (Lakeview). Did the speed test right at the store and got 2.5/0.20 Mb/s. Was really disappointed. When I got home it went all the way up to 5.63/0.55. I'm 8 blocks from the store (Diversey and Clark) - so YMMV.
