Hi! Bought the Dock for my iPhone 4 but didn't fit. Threads from this forum suggests that the iPhone 4 will fit (with bumper) the universal dock without the adapter. Before I get a used one from Craigslist (the seller told me it works with iPod Touch 3rd gen) I just want to confirm that the iPhone 4 will work (charged and play music). I'm planning to use it with Belkin Grip Vue case.
