Will iPhone 3Gs fit into iPhone 3G cases? Any difference in size/Controls?

The 3GS is physically IDENTICAL to the 3G so it will fit into your case exactly like the 3G did. All the changes are internal.

I purchased an incase slider before my 32 GB 3GS arrived. When I put the phone in it today, it was so incredibly tight that I almost couldn't get the phone back out of it. I called the incase company and they said that despite Apple's claims that the phones are identical it is possible that the 32 GB phone is slightly thicker and is causing problems with certain slider cases. Incase is nice enough to send me a replacement (even though I bought from apple store online) when they have verified that their cases fit the new phones. My previous iPhone was a 2G so I could not tell if the new case would have fit the 3G. I guess, try before you buy.
