Synchronica originally delivered the software components to Sun on schedule in November 2007.
Having accepted the software, Sun has agreed to pay, in three equal instalments in February, July and October 2008, an initial licence fee of $1.8m for the first major version of the software.
Where applicable the US firm will pay further licence fees on a per-user per-annum basis.
Carsten Brinkschulte, chief executive at Synchronica, said: "We are delighted to have received Sun's acceptance of all the licensed components of Mobile Gateway."
