Opera Mobile 10 Beta has stormed into our Symbian world providing us an amazing user experience but recent reports on the N97 are not so favorable due to the low memory effects but here is a tweak that could be used to manually configure OM to give you a little extra notch.
On the url box type opera:config
Now Opera Mobile will open some wonderful hidden screens. Here you have lots of configuration options, there are two of special interest; the first one is “disk cache” under this one you will find an option called “size” changing this from the default 4096 to 2048 seems to have a positive impact in N97´s memory usage:
Change it to 2048 from the standard default
Now go on and type opera:drives and you’ll see you’ll be able to use Opera Mobile 10 Beta as kind off a bare bones utility task manager.
here now you can type opera:about and get all the general in depth information about the app, all in all there are quite a few options so just play around and see what you find.
