Thanks to Frits for pointing this o2 Atom information and at threegmobile.net. There’s also stack of real pictures of the device which can be seen by clicking on the thumbnails. O2 showed off the Atom in Hong Kong during a new customer service centre launch.
The O2 Atom is smaller than O2 mini (iMate JAM / SPV M500) – just have a look at this comparison shot – however there’s no news on a release date in Europe :( The article states that the O2 Atom comes with a 262,000 colour 240×320 QVGA screen, 2 megapixel cam with flash, FM radio tuner and much more.
