Hi people, I just wanted to share with those of you who like jogging, biking, trekking et all my last discovering. It's an armband, rather cheap that I bought at Decathlon. It bouth it at one Decathlon's shop at Brazil, but I'm sure it's available at other locations. Less than R$30,00 (12 € aprox). It matches more or less the size of my N900. I only needed to "hack" it in order to do a little hole for the headphones, but it was two birds killed with one stone as it contributed to keep the N900 more tight inside the armbad. I fully recommend it.
