Surge, you can adjust the settings for the google apps under the options-button when highlighting the app, so you can have them run in full screen. It's prolly called something like 'suite-options', not sure tho cause I have a dutch I8910. Full screen works fine here.
Some errors concerning 'compatibilty' (if not all) can be resolved by running helloOX.
AFAIK you can only change suite settings for JAVA applications.
How do you cange suite settings for Youtube and Google Maps -- those are native symbian applications.
