http://www.droidforums.net/forum/motorola-droid-bionic/214870-new-bionic-ics-update-6-7-230-a.html I've seen on the 6.7.230 update zip, the file has two items, the update file and a CRC file. All you need to move to your Bionic is the update file.
As you can see, there's more than one ICS leak, which means that you can be off the OTA path, but it's possible to go back to .902 (and do an OTA to .905) if a new leak appears.
In theory, you shouldn't lose any of your data. See

Here's the basic method. Step 7 is where you reboot. The first 3 steps are included as if you've never connected your phone to your PC. If you can download the file directly to your phone then just go to step 4 and skip step 5.
1. On the phone go to Menu>Setting>Applications>Development and check "USB Debugging."
2. Plug phone into computer.
3. Press "Mass USB Storage" from the list of choices. Two drives will show up. One is MOT (Internal Storage) and the other is Removable Drive (SD-EXT).
4. Put the downloaded file in the root (ie main area) of SD-EXT (not Internal Storage). No need to change the name or extract it.*
5. Eject both MOT and Removable Drive and disconnect the phone from your computer.
6. Power phone down
7. Reboot into stock recovery (adb reboot recovery) by holding Power and Volume Up/Down at the same time.
8. Select "Recovery" by pressing Volume Down, then press Volume Up to initiate it.
9. When the robot appears, press both Volume keys in at the same time.
10. Select “apply update from sdcard” using the volume keys, then Power to initiate it.
11. Using the Volume keys, choose the file that you downloaded (above), press Power and let it load.
12. When the install is done, press Power. It'll reboot, but it'll be longer than normal (about 6 minutes)
The whole process, from moving the file into the SD-EXT card to phone rebooted is about 10 minutes. Of that, 3 minutes will be the phone extracting the files (Step 11) and 6 minutes for the install itself (Step 12). A long time to stare at your phone, I admit.
*I'm going on conjecture here, but it appears that if you change the name of the zip file to "update.zip" (without the quotes) when you do step 10 it'll find the file without you having to show it which one (skipping step 11 for the most part).
