There IS hope!... wireless hope for your MacBook Pro! Just don't expect ANY help to come from Apple. There are entries within this thread that give instructions on WIRELESSLY syncing your NON-LION Mac's Calendars and Address Book Contacts to your iPhone through Google. There are also links within Google searches that will help you repair every wireless syncing issue that you might likely come across. The ONLY thing I am aware that iCloud is doing for me is keeping my me.com email address alive. That's it. I, like countless others, have turned all the rest off, and I am syncing well with no cables, using iCal (with all 9 of my calendars) and Address Book (synced seamlessly and usually instantly with my Google Contacts) and Mail (handling numerous various email accounts for me) and all on my Snow Leopard MacBook Pro and my iPhone 3GS. Start by setting up a gmail account (which is free) and then proceed to change the sync settings on your devices to point them to Google servers, but ONLY after backing up everything just in case you have a problem. There are some scary points along the way when it asks if you really want to delete all of the calendars from your iPhone or replace the Address Book on your Mac with your Google Contacts. Merging may leave you with the task of deleting duplicates, but it is still doable. You can decide at that point if you want to risk losing info or deal with the duplicate calendar entries and/or contacts later.
I am not prepared to post all the instructions, since I worked out these wireless syncing issues over the course of the past several months -- and most of my information came from some very well-informed people from within this thread. It takes a lot of patience, and the time it takes will serve to make you even more angry with Apple as you go through all the necessary steps, at least it did with me.
I am still just as frustrated and angry with Apple as ever. Apple was scoffed at in its early years as being just a toy when PC's were considered the only serious work computers. And just as Apple became commonly accepted as a serious business tool, they came out with an operating system that is geared once again towards kids with pricey toys who are not disciplined enough to save their work as they go. Apple Support will tell you they are sorry, but Apple is only sorry that we are not falling in line and drinking their Kool-aid. They have now left a HUGE void in the personal computer realm, with no more support for Snow Leopard -- only the hugely expensive downgrade to Lion.
But Cheers to Google! They are offering free support for those of us who were dropped by Apple. There are likely others, too. I just don't know who they are. But as long as Google works, I will be their cheerleader, just as I once was for Apple. Thank you, Google!!!
