Icom today advised of yet another firmware update for the F7000 P25 series radios. It is listed as a critical update. The dealer info page says:
Notice:

Due to the large number of updates and bug fixes in previous firmware and software revisions, Icom is only posting and supporting the latest version of Software and firmware for the F7010 series radios. We strongly recommend that all radios be updated to the latest levels.

So Motorola ain't the only one with problems caused by firmware fixes. Oh well.....
