Nokia RM-977 affordable 4.5-inch Windows Phone being tested
A shipping manifest from Zauba lists 43 units of Nokia RM-977 being shipped from Finland to India for "intercompany use for testing and evaluation purposes only."
Details are scarce, but the phone is supposed to have 4.5-inch display and the price is listed as Rs. 8000 ($130) which is about the same price as the Lumia 520. The site also lists a dual-SIM variant of the RM-977 which too will make its way to India for testing.
