I finally got it to update but had to a couple of things first that were important. I deleted all my message and drafts, then cleared call history and cleared cache from facebook and gmail. I then followed the instructions below from another reader on another forum and added a couple of points. So if this has been duplicated, I apologize. Try it and if it don't work, clean more application. I did not need to remove my SD card!.

This is what I got to work to get the 4.08.605.2 update installed successfully on two different Incredibles, both stock/non-rooted, one with a lot of extra apps, and one with only two extra apps. It looks like a lot of work, but is actually very easy to complete, and NO factory reset is required:
- Move as many apps as you can to the SD card (for those having issues accessing them on the SD card, the upgrade to 4.08.605.2 cured this for me).
- Clear out as much text messaging space as you can, especially images. Alternately, you can delete them all. Messages eat a lot of processing memory on these phones.
- Hit the Clear Data (and/or Clear Cache) button on large use applications (email, Gmail, facebook, etc.) After doing this, do not access those apps until after installing the update. For some, you will have to sign in again, but no data was lost since they're synced items. (To do this step, go to Settings > Applications > Manage Applications, select the All tab at the top, and go into each app you want to manage.)
- Press & hold the Power Button and choose Restart.
- As soon as the screen goes blank, press and hold the Power Button and the Volume Down button at the same time.
- A white menu screen will appear, it will take a second and it will perform a small self-check. Then using your Volume Down button, scroll down one spot to Recovery and press the Power button to select it. The phone will immediately show the HTC Incredible screen.
- Then a black screen will appear showing the phone and a red triangle with exclamation point, at this point press and hold the Volume Up button and then press the Power button. Using your Volume Down button again, scroll down to Wipe Cache Partition and press the Power button to select it. This will not delete anything on the phone, just clear a stagnant memory cache.
- After this is complete, select Reboot System Now. Let the phone restart completely.
- Go to Settings > About Phone > System Updates and see if the update shows. If it does, simply select Download or Reboot & Install. If it fails again due to "not enough memory", you need to clear more apps and data and repeat the above steps until it works.
- If the update does not show, back out to Settings, account & sync, then uncheck backround data. The go back to settings and choose Date & Time, uncheck the Automatic box, and set the date 1 year ago from today (11-xx-2010), and hit Ok. (going forward a couple of years also works!)
- Return to About Phone > System Updates, it may still show "Your system is currently up to date." Back out and then go right back in to System Updates. It should be downloading the 4.08.605.2 patch update file. Reboot and Install when it prompts you. If it fails again due to "not enough memory", you need to clear more apps and data until it works.
Give it time to install, on one of my phones it took only a few minutes and on the other it took closer to 10 minutes. On one phone the Droid eye appeared for only a minute and then the phone started up completely and on the other it appeared for closer to five minutes. After the install, remember to return your Date & Time to automatic and recheck your background data in account and synck.
For any apps that aren't accessible and show up with the Droid icon, you should be able to select and remove the icon and simply add it back from your App menu. Alternately, you can re-download it from your Market.
