All's well for me after reapplying the patch.
I went in this time using Property List Editor (I've learned to love it for editing these things).
There was an interesting bit, though. I encountered an entry entitled Services. (Beneath the InheritsFrom array) One of the entries (the number zero) was the setting for the icon. The other was a setting for com.apple.bluetooth. The Service Properties was entitled "DisableBluetooth" and its boolean value apparently defaulted to "Yes." Before trying to sync up, I changed this value to "No."
I'll never know if it made a difference or whether it was a dynamic setting, but... for the text-only kids... make sure your Metaclasses.plist entry resembles this:

<key>com.motorola.V710</key>
<dict>
<key>Identification</key>
<dict>
<key>com.apple.gmi+gmm</key>
<string>Motorola CE, Copyright 2000+Motorola CDMA v710 Phone</string>
</dict>
<key>InheritsFrom</key>
<array>
<string>com.motorola.usb-bt.0x22B8/0x4902</string>
</array>
<key>Services</key>
<array>
<dict>
<key>ServiceName</key>
<string>com.apple.model</string>
<key>ServiceProperties</key>
<dict>
<key>ModelIcon</key>
<string>MOTV710.tiff</string>
<key>ModelName</key>
<string>V710</string>
</dict>
</dict>
<dict>
<key>ServiceName</key>
<string>com.apple.bluetooth</string>
<key>ServiceProperties</key>
<dict>
<key>DisableBluetooth</key>
<false/>
</dict>
</dict>
</array>
</dict>

paying particular attention to the ServiceProperties key.

This did indeed fix the problem, thanks.

this worked for me also just today. i saw a similar reference to not disabling bluetooth in
