A very strange thing. I can't send any more photos from my iPhone. I select the photo, Email Photo, add a e-mail address and then I click Send. It stays a couple of seconds, the circle animation appears near the WiFi and then it goes back to home screen. (it doesn't matter if I try to send it thorugh my me.com account or another one)

If I remove my me.com account it works.


LATER EDIT: I've just noticed that I can't send photos to addresses which are in my Address Book. If I try to send them to new e-mail addresses it works...
