Just in time for that rumored late September/early October launch date for the HTC Jetstream (Puccini) AT&T has already begun flipping on their 4G LTE switch in some lucky cities. According to BGR, some AT&T customers in Chicago are reporting that their 4G LTE mobile hotspots devices have lit up with AT&T’s trademarked “4G LTE” symbol. After a few speedtests, users are experiencing download speeds of around 13Mbps and 2Mbps upload.
AT&T has yet to formally announce the availability of their new 4G LTE in any market but this new development lets us know it’s coming right around the corner. Keep in mind these speeds are all based off of a preliminary soft launch and could improve by the time of AT&T’s official rollout. A mysterious Samsung Impulse 4G was also revealed in a leaked image a few days ago and is rumored to be AT&T’s first 4G LTE enabled handset. Are you guys impressed with AT&T’s preliminary 4G LTE speeds or were you expecting more?
