Funny I saw this thread.
I have had OS 3 since it was available, probably a few weeks before and I have yet to see a single notification.
I read yesterday that the ebay app was updated to include Push notifications.
I updated the app yesterday.
I have several auctions ending last night.
My iphone sat silent the entire night, not a single beep, whistle or text.
Wake up this morning and I find out that I lost one that I wanted by like $1.
Does Apple even know what push notifications mean?
Is it too much to ask to have my app buzz me at 10pm that an auction I am participating in is about to end and I am losing?
Your settings must have been off or something, I've tested the Ebay push notifications about 30 times now and it has worked flawlessly
