Modifying the CAB file to change one word seems excessive. If you follow these steps, you can modify your own config file:
1. Locate the directory where the Bing app was installed (this depends on whether it was your storage card or internal memory )
\Program Files\Bing\
2. Locate the "Bing.config" file.
3. Open the config file (or a copy of the file if you want to be safe) in any text editor, whether on your PC, Mac, or on the phone itself. ( I copied the file to a PC and used Word Pad.
4. locate this line:
<add key="UseAppServerUpdates" value="True"/>
5. change the above line to the following:
<add key="UseAppServerUpdates" value="False"/>
(note: you changed one word from True to False)
6. Put the modified file back where you found it, with the same name as when you found it.
7. Launch Bing. Turn on GPS or do whatever you usually do to get the nag. You shouldn't get the nag anymore.
good luck. I don't think posting the modified config file is a good idea either. I don't know what device specific settings are in it, even if it's from another Intrepid.
