Increase Max Upload Size

Hi:
I can't seem to increase the maximum upload sizes for any of my blogs - stuck at 2MB. I've implemented the php advice as per: http://wordpress.org/support/topic/how-to-increase-the-max-upload-size
In both:
* in php.ini
* wp-config.php

** To no avail. The api's continue to report a maximum of 2MB regardless of what I seem to do...
Is there a way to locate where this limit is coming from?
