It’s not too often that smartphone manufacturer’s leak info on their own unannounced device but it appears that’s exactly what the Nokia advertising bods have done in the form of a picture of the unannounced Nokia 5250 handset.

According to an article over on Intomobile by Stefan Constantinescu, and by way of Love My Nokia, there are no confirmed details available at this time on the new Nokia 5250 device as only the image was carelessly leaked by Nokia.

However Stefan, based on what they know, assumes the Nokia 5250 will be a low end handset probably commanding a price tag of under €200 or even maybe €150, and more than likely will have the same specs as the 5230.

Those specs would mean a 3.2 inch display, 3G. GPS and a 2 megapixel caerma, and should be announced by the end of summer and hit shelves in time for Christmas. However Stefan does admit he could be wrong but also reckons that this new Nokia 5250 design closely resembles the Sony Ericsson Xperia X10; what do you think?
