I messed up my 808 when I installed an old version of Microsoft Apps, thought there was a good email program in it but when I was finished I found out my 808 looked like my old N8 without FP1, the Gallery for example was the old one and I could mark several pictures like before but icons for editing and more was messed up and got lots of errors...still this means the 808 contains old hidden programs....cant believe the old Gallery was copied into my 808 via Microsoft Apps 1.0....even after hard reset the old Gallery and much other things was way way old looking...that I take as it actually is possible to downgrade when not a total reset of factorysettings didnt helped me...soo, I made the decision to upgrade to FP2 when I had FP1 before...and then everything was ok again...and I have to say the FP2 was really good....found out the missing arrow keys for messaging actually are not missing..they just appear when needed and pressing on the text trying to put the marker where it needs to be...when doin that the arrow keys comes up as blue for 2-3 seconds...smart! 
Was very very hard to find the alphanumerical keypad though...but atleast I have it now and it works good everyhting!
Even found some new updates in NokiaSuite for various functions in the 808...which have come after the FP2...
Gotta love Symbian Belle...please continue to refresh it with smaller updates now and then, dont kill it!
