I dont get very good service on my evo, and it has pretty bad battery life. i hear flashing a radio update can help a little bit. will certain radios only work with certain android or software versions? im running freshs 220.127.116.11, so i have android 2.2 and software 3.26. if i flash a radio update and i dont have the right software installed will i go into a bootloop? where can i find radio updates compatible with this rom?
