The ICS OTA has been released from HTC Elevate for the HTC Sensation XE, build number 3.32.401.105. This should be the final XE ROM for ICS on the Sensation. Kingsrom has been kind enough to patch the OTA in a flashable build which is stock and rooted.
There are two versions available, an odexed version and a deodexed version which can be found here (all credits to kingsrom for the work)
(This can be used on a regular HTC Sensation as well the XE)
(3.32 Firmware is required, update the firmware before flashing the above)
