In your original post you said; "I can sync from my computer to the iPad app just fine, but apparently not to the iPhone."

Now it looks as if you meant; I can sync from my iPad app to the computer just fine, but apparently not from the iPhone.

If this is the case, your problem is most likely a username / password problem or the "No Logs to Sync" message is correct. Did you actually put data into the iPhone app, prior to hitting the quick sync button? If there was no data input then you will get the "No Logs to Sync" message when trying to sync / upload data.
