@leocg Wow, that's sad. I have a Nokia E63 running S60v3 with OoeraMini v7.1 that still shows syncing activity only that it doesn't reflect on my account or other Opera browsers (Android and Windows versions). Guess l have to manually export all my bookmarks and speed dial content to the others.
If you try to gzip all the text that is on the page, you get 44kB of data. You could possibly go below with some different compression algorithm, but not very much.
Opera Mini compression will be visible more likely on some more advanced pages with CSS, JS, images etc. On the page provided, there's simply not much that can be compressed.
