Windows Mobile 5 uses digital code signing to verify the origins of digital content. When deploying SQL Anywhere to a Windows Mobile 5 device, you can deploy either of the following types of .cab files:
Pre-built, signed .cab file The SQL Anywhere installation includes pre-built .cab files that are signed by VeriSign. When you use these .cab files, you do not receive an unknown publisher warning. Files are supplied for both version 1.1 and 2.0 of the .NET Compact Framework.
Custom, unsigned .cab file You can build a custom, unsigned .cab file to deploy SQL Anywhere to any supported Windows CE platform. On Windows Mobile 5, running a custom, unsigned .cab file results in an unknown publisher warning, but does not affect the installation of the software.
