Build: 1.53.531.7 CL47441 release-keys
Kernel Version: 3.0.8-01052-gd5010fc
SMP PREEMPT Thur Mar 29th 19:02:02 CST 2012
I had a pre-release version of the phone with the same everything, except the kernel was dated Mar19th. After rooting it, I got nonstop problems with wifi. (phone would get into a reboot loop if you ever connected to any wifi network)
I had exchanged the phone with HTC, hoping that the replacement would have the current baseband/build/kernel. Unfortunately my replacement had the same everything, but with a slightly newer kernel.
Currently I am stil waiting to hear back from HTC to let me know if there will be an update that updates my baseband, or if they want me to exchange my phone again. I have held off on rooting this one because I'm quite positive it'll have the same wifi issues once rooted.
