Does anyone know if all the S60 5th Edition features of Nokia 5800 /5530 are the same features that are in the new Sony Ericsson Vivaz.
For example, I use search a lot and the Message Reader and the Say callers name.
Because the Vivaz is S60 5th Edition, does that mean these features are automatically included?
All features in a specific model based on the same Symbian/S60 version are not necessarily present in another model based on the same versions. There have even been differences when the devices comes from the same manufacturer.
Of those particular features you mention, I don't know if they're in the Vivaz or not.
