Opera mini,opera mobile and other apps disappeared after Belle update

It's just a guess but I think it has to do with the RAM(Random Access Memory).
The C: disk is just 251/256mb, that is the same amount as the RAM. I guess that the OS files were to big for the old location so they had to be moved. But normally (pc's, laptops etc.) RAM is many times faster then normal storage, don't know if it makes not much difference with a phone. That's my best guess.
If the RAM in a phone is about the same as in a pc, the above stuff is incorrect because RAM does not hold permanent date. Thats for the ROM (Read Only Memory) which would be 512mb in the N8.

I read at Nokia's official forum that lots of people lost apps because of the update, me included.
I also noticed that the Nokia Live/City View (from Nokia betalabs) doesn't work on Belle, this is already reported.

Belle downloaded well, but I did lose some apps. However I have downloaded them afresh from Nokia Store, even downloade Sygic without being charged again. Unfortunately Sygic are abandoning Symbian which is a shame as I preferred it to Ovi satnav.
