And apparently Opera Mini 4.5 will still be functional. It will just lose the ability to synchronize. You should not be losing your bookmarks or your notes. Also, read this and follow this thread:

This tool will work for bookmarks. Not sure if it'll work for notes.

I still used Opera Mini 4.5, but don't know if it'll still work in December or after December. I'm starting to use Opera Mini 8. I like the tabs and select text tool, but AFAIK it no longer has the landscape mode nor am I able to use #3 to go to top of page and bottom of page. (The #3 shortcut is now a "find" function.)

I believe that you can still sync your bookmarks, speed dial and notes. Isn't speed dial just 9 bookmarks? I think you can have more than 9 on Opera Mini 8, but you can only use the *_ shortcuts for the first nine.

It tells you a way to sync if link.opera doesn't work. I can't remember how I did it, but just login to to sync on your Opera Mini 4.5, sync each individual bookmark, then they will all appear on Opera Mini 8 once you download it (Opera Mini 8), install it and log in to sync. I'm not sure, but I think you should be able to sync your notes using the same method. Good luck and let us know if it works for you!

It might be a problem on Yahoo's end (on purpose or by accident), but I can no longer access Yahoo Mail. I can check everything else Yahoo-related (e.g., weather, sports, contacts) but not Yahoo Mail. AFAIK there isn't an adblock software on my phone that I've installed, and while I've had problems with Yahoo Mail before, it's always been temporary and I've never had problem just accessing the URL. I can't even access it via Yahoo.com even though the icon shows that I have two email messages. I can access it from home (where I DO have Adblock software installed) just fine; I'm only have trouble connecting to Yahoo Mail on my Nokia, via either Opera Mini 4.5 or Opera 8. I borrowed my friend's iPhone to access it directly via internet and there is no issue. Can anybody help? Does anybody else have this problem?? Thank you very much for reading and any light you can shed on the situation or a solution, if one exists. Haven't been able to get in touch with Yahoo tech support so if anyone has an email address for Yahoo Mail support it will be appreciated. Thanks!!
