Snow Leopard - support

Well, 10.5 to 10.6, not a big jump, but installing a new OS always worries me, what will work and what will break? In this case, no support needed - have spent the rest of the day tweaking the OS + google + iPhone, their still not working together in the way that I want them to do, it's probably an inbuilt failure to make me pay for a mac mobile account.
More reading to be done ....

Will do my best to catch up in the week (have been very lazy this w/e)
