I do the Power + Volume down and once I get to the white hboot screen, it starts doing it's check. I will have ot start deleting those zips after I'm done with them, for this reason. I can take the SD card out, plug it into my computer and home and remove the file no problem at least.
for what its worth,the checking its doing wont hurt you... you can let it read the file and check it... you will be then presented with an option to update or not. you can chose no,then select recovery.
if you dont have a rom on your sd card to flash,you can remove it and put in an adapter as you said,or you can just get into recovery,then advanced options,then toggle usb on. this will mount your card to your pc in recovery so you can delete the file,and put a rom on to flash,if needed.
Yes you could do that. I would suggest that actually since your back up seems to be corrupt. I would suggest making back ups in CWM and not using Rom Manager, I have seen a few reports of this from backup made in RM.
Key thing here is, don't panic... You are not bricked (not even close) and this can be fixed. Deep breathes young padawan, we will get you back up and running.
good advice here, youll have your phone back in no time

and i agree 100% about rom manager. ive seen it do all sorts of terrible things to people,lol. you really are much better off using revcovery to flash,wipe,backup etc.
edit: ignore what i said above

i just put the radio file back on my phone and tried it... selecting no to the update only gives you the option to reboot,wich does you no good.

so looks like sticking your sd card in the pc is the best way out of your predicament. delete the PG05IMG and then you can get into recovery and fix it
