Dear ajk23az,
I understand your frustration with not receiving Gingerbread on your device by the end of Q2. This was an early projection for the Gingerbread update for your Thunderbolt. I do apologize for any frustration or confusion this has caused. We have yet to receive a release schedule for Gingerbread. When updates are announced, you can find the information at HTC - Mobile Phones, Smartphones, Cell Phones, PDAs and HTC (htc) on Twitter.
Sincerely,
Lisa

Pretty generic response IMO.
