T-Mobile’s LTE sightings have ramped up again this week with a host of reports coming out of Dayton and Akron, Ohio; San Diego, Anaheim, Fresno and across San Bernadino county in California. Last but least are a few sightings popping up intermittently out of the Boston area. San Diego is the clear winner here as the lions share of emails I’ve received since Monday show off plenty of network activity across the area with a number of tests pictured below.

As per our usual warning, these sightings are unofficial and represent what we believe is T-Mobile’s “fine tuning” and “testing” stage prior to launch. However, all three of these markets are listed as set to launch before the end of June so there’s a good indicator we aren’t far off from an official launch. So I wouldn’t jump too far ahead and assume that a LTE sighting means an entire market is live.

Am I missing your city?
