iTunes 8.1 and jailbroken iphone

[theodotcom]

Has anyone upgraded to itunes 8.1 with their jailbroken iphone, does it work ok.
Basically this is the situation... Im currently doing a reinstall on my laptop that has my itunes installed on.
When I install itunes 8.0 it say it needs quicktime to run, i install quicktime but itunes cannot see it and the apple upgrade box pops up giving me the option to download itunes 8.1+quicktime.

There was no way around this so I had to download it, if I connect my iphone to it will I lose everything? or will it just copy the apps to the new itunes? is there some sort of software to migrate an iphone to another computer etc etc.

Need to keep contacts/sms/emails etc.

Any help appreciated.

yeah I think it will be fine, I have used various itunes versions with my JB phone, it will ask you if you want to update the firmware, just say no

I've got 8.1 iTunes and a 2G iPhone fully jailbreaked... no problems at all that I have seen

Backup your contacts etc before you upgrade, then once upgraded just "sync" them all back accross with iTunes
