Radio Updating

[rdragona1994]

I have a T-Mobile HTC Sensation rooted with S-OFF with the following specs:
HBOOT-1.27.1100
RADIO-11.21.3504.12_2
Running Ice Cream Sandwich 4.0.3 build 3.24.401.1

I want to install the InsertCoin ICS RC1 4.5.2 rom but the specs required are at least HBOOT-1.2.7 and RADIO-11.68. The question is, how can I update my radio to the minimum specifications or am I fine where I am?
Many thanks

Can anyone help? I've been doing research and I know I'll need a new firmware with the specs. The phone is SuperCID now.

Got it already.
