Hi, I recently bought HTC Sensation XE with Beats Audio Z715e. The box gave manufacturing details as October 2011. Updated to ICS after purchase - Android 4.0.3 Sense 3.6 Software 3.33.720.106 Kernel Version 3.0.16g31a4fc7 htc-kernel@u18000-build-144#1 SMP PREEMPT Baseband 11.76A.3504.00U_11.24A.3504.31_M --- HBOOT Screen: *** LOCKED *** PYRAMID PVT SHIP S-ON RL HBOOT-1.29.0000 RADIO-11.24A.3504.31_M OpenADSP-v05.6.02226.00.0418 eMMC-boot Mar 2 2012, 18:14:34 --- Is this radio latest and good enough?
