I finally went ahead and permanently deleted my extended ROM.
WOW it made a world of difference - I can't emphasize enough that it's a
MUST DO on this ROM..IMO. After having only .o1mb of free space in the ExtROM it eventually forced me to follow the link given in the first post - which directs to here:

It was a pain in the ass to go back to original SprintROM, lose my radio, retrieve my radio, then go through all the steps necessary to permanently delete this junk... but now I'm a proud new owner of a beautiful 10 mb of joy.
