more about personal experience:

Good news:

Significantly faster response when opening phone, SMS, ipod
Webpage load much faster- almost nothing to do with my edge connection

Bad:

Cydia keeps sending me back to home page- so in my case, it is not fully working as I claimed before
Cannot open snapture- not supported? Can anybody clarify this?

About the back up, give itunes 8.0 a try, I believe firmware 2.1 comes in handy with itunes 8.0. When I was on 2.0.1, the backup seems to take infinity period of time (keep hanging or took at least 5 hours to complete. Whether I reboot the phone or just cancelled the back up

psyeo,

same problem here

same here oso =/ ( couldn't restore the backup )
lost all contact and messages ...

mine restore back no prob, coz i used iphone pc suit to backup..

woot i thought iphone pc suit is language translation ...
sad =/

After updating mine, helped my gf and sister to update theirs' too. Everything works like a charm now.

winpawn out?

problem solved, you need to replace the mobileinstallation file with a newer version.

My friend wants 2.1 custom restore firmware from PwnageTool, I have successfuly pwning my 2g with it. I reckon if I pass him this custom IPSW, he should be able to use that on Itunes 8 on a PC. Since bootneuter is already in the IPSW right.

Just to confirm with you all. Just pwned my iPhone 2G with Quick Pwn and iTunes 8.0. Running firmware 2.1... much better than 2.0 (I skipped the updates in the middle)

how do i update the mobileinstallation file/

hmm did u patch the mobileinstallation file in mobileinstallation.framework before? if you hvnt, that means that the backup problem is not related to that

if u did, here is the new patch file for mobile installation Link

you need to patch the file into /System/Library/PrivateFrameWorks/MobileInstallation.framework




rarara...why can't i concentrate on my essay that due in 4 hours =.=

Thanks psyeo, i will put this up on first post.

Thanks mate.

what this for?
to enable backup via itunes8??

nope, the backup problem that I come accross is because i use an older version of Mobileinstallation patch on it.

If you have not patch it or didnt face any error while backing up, u can ignore that

Need help here~!!!
When I reach to create Bootloader v3.9,although I select the file correctly,it still show me "Sorry,but that doesn't appear to be a proper file"
Can I know how to solve it?I tried so many BL3.9 from other website but still can't:(
(This is the first time I face this problem.I don't have this problem when I upgrade from 1.1.4 to 2.0.2.)

Wooo...gud job david..Nice2, but hey..im not in a hurry to upgrade from 2.0.1..haha..not much problem except sometimes my "stanby mode" phone cant be recovered unless force restart (hold power n home button) or just tap2 any button tilli recover..lol..(happen since i upgrade to 2.0)
but nvm..i can bear sumthing like that.
