share some but not all apps/settings between 2 iphones

[vistadude]

I have an iphone 3G and soon getting an iphone 4. I'd like to sync them on the same computer and with the same iTunes account in order to share contacts and some, but not all of the apps. How do I go about doing this?

Thanks.

What I would do is, as usual, make a backup of your 3G and then restore this backup to your iPhone4.
This way you have 2 'identical' iPhones. Afterwards you could just deselect certain apps and/or settings
for your iPhone4 that you don't need or want.
