AT&T will launch HTC’s 10-inch tablet, currently codenamed “Puccini,” as the HTC Jetstream according to a new report. We brought you the first solid leaked images of the Jetstream and have heard rumors that it is powered by a 1.5GHz dual-core processor and will support AT&T’s 4G LTE network. HTC’s chief financial officer Winston Yung confirmed on Tuesday that the Puccini will launch in September or October, although AT&T may choose to announce it later this year. AT&T’s 4G LTE network will go live in five markets this summer and the carrier hopes to expand it to a total of 15 markets by the end of the year. That seems like too small of a market to launch an LTE tablet into, and AT&T hasn’t promised any 4G phones or tablets this year, but we can still dream.
