In what seems like a confirmed tip, full touch Nokia Asha family gets two new memebers 308 and 309. Asha 308 seems to be the dual-sim version while Asha 309 seems to be have wifi as its top feature and as expected should go cheaper than Asha 311.
There are some pics as well which may or may not be the Asha 308 and 309. But check them if you are interested.
