It is a tight fit putting the iphone onto to dock. And each time I dock the iphone, I have to remove the protective cover (I bought the Incase Protecter). Surely, I think the design could be improved right?
Two-stars due to high cost of a solution that was included with the original iPhone and is NOT with the 3G iPhone. Read the product descriptions of what is included and compatible carefully before buying.
I too was puzzling over what to purchase for my new iPhone 3G which had no dock included (unlike the first iPhone) - I was very disappointed!
You have to purchase the Apple Universal Dock Part Number: MB125G/A with this iPhone 3G Universal Dock Adapter, I believe. That product is expensive at $49 but does include an Apple Remote (but no cable!!).
You cannot use the original iPhone dock as it is not "universal."
If you scroll down to the bottom of the descriptions of most accessories for iPods and iPhones, they note issues like this by leveraging icons to help understand what is and is NOT supported. I am going to purchase both as the 3G iPhone dock adapter indicates it works on the universal dock. If not, I will be returning and asking for a full refund!
