Some good ‘ol clumsiness from a Nokia employee has just revealed some information about upcoming devices from the Finnish giant.

An accessory, the Nokia Medium Universal Pouch CP-594, revealed a bunch of supported devices, which aren’t announced as of yet. The Nokia 305, 306, 311 and 605 have been named and should all be medium sized devices as the accessory’s name suggests. The 306 will be a touched based entry level device, the other two 3xx devices will also be lower end. The 605 however is a mystery, it could be another WP Refresh Lumia device or a new Belle device.

Until some more information appears, we can only speculate, but it’s safe to say that Nokia may announce them all, together with the Lumia 719 at Nokia Connection in June.
