We've already had the first wave of information on when the new Sony devices announced at IFA will be available, but any information on price is still somewhat lacking. At least one British retailer has tagged a price on the entry-level Xperia J, despite not being able to offer it themselves until October.
Clove Technology has come out and priced the Xperia J at £190, but will not have stock available until late October. This is a little after the September 5 release date previously supplied by other retailers, but it's the first indication we've received of a UK RRP for the new device.
Clove also intends to stock the full range of colors for the Xperia J, but notes that the first units will only be available in black or white.
