Returning iPhone 4 after 30 days?

You'll have to find a way to return the phone before the 30 days are up or you won't be able to return it at all. The current return policy is an exception to the normal return policy so it is extremely doubtful any exception will be made on top of that.

did Steve Jobs not say something about the returns in the press conference, as in the UK we only had 14days to return it if bought from the apple shop. and believe we have now been extended to 30days or till the end of this month. i am not sure about this tho.

The return for a full refund only occurs within the 30 days, after that window period is over you can not return it for a ful refund. Sure you could try returning it after the 30 day window but with a fee.

Ring up the store, get a return authorisation number, post it back from where you are currently.

Obviously if you don't have the box with you then it might be trickier.

Look at it this way, if you're in France, a LOT of things could be worse. Enjoy!
