New firmware for N-Gage...

I asked in my near nokia shop in Greece and they told me they have new firmware for the N-Gage version 3.30.1.13 and i will go to upgrade.
Does anybody knows what it fixes? When you upgrade the firmware you lose all your program and game settings?
Is something i can do to keep them (i copied the c: contens in my mmc)
Is it going to work after i copy the settings back with the new firmware?

Thanks!

y not u let us noe after u try? hope it works, im gonna get mine flashed too. i sure hope the new firmware lets u use more brands of 256/512 mmc, and haf more options, like sending stuff via bluetooth straight to mmc wifout using pc suite.
