My home button on my iPhone 3GS has been slowly dieing, I'm now having to press it 2-3 times REALLY HARD to get it to register. I've sent it off for repair, but asking around the office we have two other people which have 3GS's which are having similar problems to a lesser degree with the new 3GS iPhones.

All those users and myself have had 3G and 2G iPhones with no problems... Wondering if it's a more widespread issue, we all got our iPhones at different times (6 months or so apart) so it's not a bad batch per se.

Or perhaps it's just a coincidence.

Anyone else having problems with the home button on 3GS phones?
