I have so many issues with sync I can't be bothered to list them all... seriously.
In no particular order:
1. iTunes opens all by itself, apparently kicked into action by my iPhone over wireless. I close it, it reopens 3 minutes later. I tell it not to by unchecking the box that says to not open iTunes when iPhone connected, and it says... sorry, can't find an iPhone to sync with, after having repeatedly opened iTunes because of it.
2. When I do get it to work, it syncs and then decides, no, I will wait 200 days + on applying changes.
many many many more issues, all around sync.
Tell me... how can I trust my iPhone on Wi-Fi, if I have to sit there and watch it do it to see if it is successfully, all the time. I have to have my iPhone next to my computer, plugged into the mains, next to the computer but not in it, just to hope this features works each time. I am on my knees, watching it intently. I waste a lot of time, because half the time it doesn't work, so let's say, 30 minutes of plugging and unplugging, and then 10 minutes of watching it to see if it finishes. 40 minutes each day.
The worst thing is I can't give up and go back to just using the cable, because whoever designed this shanky flaky wi-fi syncing software, made the same screwy changes to cable sync too, so it acts in exactly the same way... unreliable, unsure of itself, unpredictable.
The ads show them just leaving that thing docked and syncing through the noght - if I trusted my iPhone to do that, I wouldn't have an iPhone by morning. I would have a shiny brick.
I shouldn't have to hold iTunes' hand and babysit it through. Seriously, and I mean, seriously, they Cannot have fully tested this software before releasing it. Ego kicked in and they assumed their brillance "just works" because SO many people are having all of these issues and more.
Their programmers need to be paid a hack of a lot less if this is the "AOL" type work they are going to be doing from now on.
