Of course, as with all broadband mobile speeds, these are “theoretical” speeds, meaning the likelihood of you actually hitting 42 Mbps are fairly low, but you should still see some pretty significant speeds when you are out and about doing … well … mobile things.  The 41 additional cities added today brings the total to 96 with more to come this year.

Have you gotten to experience the increased speeds yet?  How were they?

UPDATED: A total of 41 additional cities were rolled out today, not the 42 that were originally reported, bringing the total to 96.
