Sony Mobile changes the way Xperia Lounge membership works
Up until now, Xperia Lounge membership was split into two: Gold and Silver. You did not have to pay anything for this membership, as the differentiation was made by the device you owned. Basically, all those who bought flagship Xperia phones were offered Gold memberships, while the rest would get Silver memberships.
Well, that's not the case any longer. Sony Mobile has decided to discontinue Silver and Gold memberships and allow everyone to get the exclusive content would make available for free.
If you own an Xperia smartphone, simply open the Xperia Lounge to get access to exclusive content, competitions, offers and other stuff Sony Mobile plans to make available through the service.
