@Jan-Dirk we are updating Icenium templates to latest Kendo UI Mobile and jQuery mobile versions if they pass some basic tests so expect it with next Icenium release.
Note that as general rule existing project do not get auto updated as this can bring unexpected compatibility issues with user code.
If you wish you can create feature request
so our team will bring some smart solution for this scenario if there is high demand about it.
All the best,
the Telerik team
