i tried it again and this time it didnt restart my phone and the last line it showed was this 'Setting up mp-fremantle-generic-pr (20.2010.36-2) ...
', then i checked to see if it shows in app manager but still deosnt

All well. Just go on and repeat:

apt-get install mp-fremantle-generic-pr

until you can see the latest version (20.2010.36-2) in Settings->About product

I hope your battery is not drained to zero in the middle of installation

hey i tried it again and it says generic pr is already the newest version

You have successfully installed the latest version of Maemo. Congratulations!

yes but it still shows the old version in settings -> about product

I,I,I don't know.
First, what catalogues do you have in Application Manager?
Second, you could try to restart the phone, though it's most likely pointless.
Third, try:
apt-get update
apt-get upgrade
