App organization in iTunes does not transfer to iPhone

I have an iPhone 3G and just purchased a new Mac Pro. I successfully transferred all my songs and apps from my old Mac to the new one. However, when I synched my iPhone for the first time, it placed all of my apps in alphabetical order (except for the native iPhone apps on the first screen).

I used iTunes to arrange the apps back the way I wanted to, but when I clicked "apply," it synched the phone and put them all back the way they were on the phone (alpha order). I used to be able to arrange apps on my computer, then transfer that setup to the phone.
This doesn't seem to work anymore, and I can't figure out why.

Any help would be appreciated.
Thanks,
