Radio is the firmware that operates your phone and wireless such as wifi, bluetooth, etc. Well for one thing there is alot of ROM and Radio version for HD2 and not all is compatible with each other. Example Energy ROM need to use Radio version ending with 50 example 2.12.
50. Using other Radio version may brick your HD2. If your radio is already compatible then there is no need to flash it.
There are too many roms to suggest one for you. Will PM you the link to xda on HD2 ROM developement. PLEASE READ BEFORE YOU FLASH as the flashing steps and precaution for different device is not the same. Meaning it will be different from the way you flash your omnia. You will need HSPL and it is recommended for you to run Task29 first. These are just some of the thing you need to know and be aware of.
Word of advice, if you do not have time to read and understand, please do not flash as one wrong step can brick your HD2.
