I developed my site ages ago, and just noticed that down the bottom it still says Ovi Maps 2010!
So I jumped on the API website and it's all updated.

After 5 seconds of investigating I thought that changing the Library I loaded would update the maps. I.e. putting in this:
<script src="http://api.maps.nokia.com/2.2.0/jsl.js" type="text/javascript" charset="utf-8"></script>

But it didn't work - still 2010 maps with the old colour scheme. To save me investigating could someone quickly let me know how to update my maps so they show more up to date looking maps?
