This is probably a joke by someone in Spain, but a Gizmodo reader just took this photo of this banner. It says "Presenting iPhone 5. Now available." It appeared a few minutes ago at the FNAC store in Madrid's center.
FNAC is a huge electronics, music and books super-store chain in Europe. Kind of like a mix between Best Buy and Barnes&Nobles. Inside they have small retail spaces dedicated exclusively to Apple gear.
Of course, even if it's a real photo and not a Photoshop, anyone can print a banner and put it there. It's easy, so take these photos with a two-tonne grain of salt. [Thanks Manuel!]
Update: As expected, this was a hoax by some imbecile Spaniards. Payasos.
