Just found out a new update of CyanogenMod 7 for Milestone A853 RC11 was uploaded, here is the download link:
Note that this is a new update on July 6, include some quick fix something. e.g fix touch-to-focus. Another important fix is Allow loading of vendor specific services from compiled jar files. This is needed e.g. for the Motorola AGPS code.
CyanogenMod 7 for Milestone is a rom which is created by Nadlabak based on offical cyanogenMod 7, many thanks to him, for bringing us the nice Gingerbread.
