Thanks Jerry, I followed those leads around a bit and the following worked perfectly:
[HOW-TO] Installing CM4DX or CM4DXGB
Enjoying CM 7.1 as we speak
this link also worked for me, flawless install. very pleased with CM 7 .... i deleted my most recent clockworkmod backup to do another backup before installing CM, but forgot to do the backup when i went ahead and wiped data/factory reset the phone. don't really mind as i like this OS it's running smooth so far.
i installed it on top of 605, if i use RSD Lite and the 602 SBF i have, can i get the stock rom back again if i need to go that route ?
