PS: John Lewis is still selling this for £499.95+VAT. This phone coloured black was first launched in London at Carphone Warehouse on Nov 17th 2011, together with Google Galaxy Nexus. Then the white version launched at John Lewis on Jan 23rd, 2012. 2 weeks after I lost my Galaxy S1. Initially with android 2.3 ginerbread, and Samsung later released android 4.0 ice cream sandwich update. Bought this phone today.
