My data is not pushing properly either. When I change things on my imac, I have to manually click the sync option before any data appears on my iphone or server. I'm glad I'm only doing the trial because this service doesn't seem worth paying for.
Hello again,
I have just upgraded to a 3G iPhone from the original and I rapidly found that nothing would push to my phone.
The fix that now has my phone working reliably is to go to Settings>Fetch New Data>Push>Off. Then turn the phone off.
Now turn the phone on, and go to Settings>Fetch New Data>Push>On. Then turn the phone off, and then on again.
Please let me know if this helps.
