I would normally discount random tweets for a rumour, but Viipottaja and Peter_L were apparently in discussion about these tweets so there may be some truth in it.
A tweet from someone based in NY, a Nokia PureView fan, said:
Finally got. Hands on lumia 9XX for verizon,can you guess it???what phone is that??? Hint wp8 of course
And another tweet that read:
Another hint: wireless charging and thinner lighter better
It could absolutely be nothing. There were some random conversations before by others about a possible Nokia Lumia 822 for Verizon and well that’s in pictures everywhere.
Could it be a 920 varient for Verizon? Some speculate Verizon would have to wait out until early 2013 for their 9XX variant whilst AT&T bask in the temporary exclusivity. Who knows.
