I've rooted my phone and running liquid's thundersense v1.3. I've read various radio threads but still very confused on which is the new radio that i should flash on my phone. And how do i find out which radio i currently have?

Baseband version is 1.16.00.0223r

software number is 1.13.605.7

Last question, i've read that when you do flash a radio that you put it on SD card as PG05IMG in the root folder. I have a file on my SD card by the same name but it is not in the root folder. If i do flash a radio would i need to delete this file before putting in the "new" PG05IMG? What exactly should i do?

Thank you in advance for your help.
