You can use XDA accessories, but which?

[Guest ragegames]

Its interesting to hear you can use XDA accessories such as the sync & charge USB cable and power supplies,

Which other XDA accesories work? anyone tried using the XDA addon keyboards at 25 quid (for a mini one) and 90 quid (for a bigger foldout one) on the SPV?

Its a bit much to shell out to try if it wont work :D

The headphones look identical too, or seem to be from the picture I saw- are they interchangeable?
