Dear XXXXXXXXX
Thank you for contacting HTC. I understand you are wanting the update for the Thunderbolt and will be more than happy to provide you with the appropriate information on why your device has not been updated. The reason the Thunderbolt never received ICS is because when we tested the software on one of our Thunderbolts, the phone was bogged down and started running a lot slower. Verizon decided that the phone functioned better without the ICS update.
I apologize for any inconvenience this causes you XXXXXXXXX. If you have any other questions or concerns, please feel free to send us another email or give us a call between the hours of 6 AM and 1 AM EST at 1-866-449-8358. Thank you for being a valued member of the HTC community and I hope you have a wonderful week!
