J'ai trouvé !!!!
lors du copié collé du fichier, je me retrouvais avec des doubles guillemets (ouvrantes et fermantes) inclinés comme ceci
“key”:“266x533”,“name”:“HTC EVO”
je l'ai découvert dans Dreamweaver avec la coloration syntaxique (dans le bloc notes de Windows je ne voyais rien).
J'ai corrigé le texte, que je joins, pour ceux que ça intéresse.
j'ai aussi corrigé les - séparateurs (comme dans
"iPhone 3GS - 4 - 4S") qui étaient lus comme des â dans Firefox.
