Dear Nokia fan clinging on to all hope that the 5230 and Nuron were two separate entities, whereby you’d have even more Espoo devices to look forward to: you’re wrong. TmoNews has picked up what’s purported to be another internal T-Mobile documentation for the 5230 Nuron. Like the previously-rumored leak , it’s said to be going on sale on March 17 with a 3.2-inch touchscreen, on-screen keyboard, and Ovi Store.
