IPhone :: Cannot Connect Since Version 3

Have had issues with my iPhone 3G version 4.0.2 connecting with my MacBook Pro. It's been awhile now that it hasn't been able to connect. It wasn't able to connect since version 3. The problem started when I upgraded my laptop to Snow Leopard. I can connect to the same exact laptop but when booted into the PC portion. I can also connect to my girlfriends MacBook which is running Leopard. I can also connect to an HP laptop. The phone charges when plugged into the wall. It's not an iPhone issue as my girlfriends iPhone also cannot connect to my laptop.

I remember looking this issue up a few months ago and from what I found, there were quite a lot of issues out there with people not connecting to Snow Leopard. Although there were no solutions then. Thought I'd do some searching today and I couldn't find much at all on it. Did it get scrubbed?

I found something on deleting Xcode but I do not have it installed. I've tried everything. I reset the PRAM, hard rebooting the iPhone, updated iTunes, reinstall iTunes, deleted cache and preferences, repaired permissions, etc. Is there a solution other than downgrading to Leopard?
