Google has refused to deny mounting speculation that it is working to produce its own brand mobile phone. Reports suggest that the web giant is developing a series of”GPhones”, centred on its mobile services, such as search, e-mail and maps. In a statement, Google said it was working with carriers, phone makers and content providers to “bring its services to users everywhere”. The firm would not say if its efforts included plans for a handset. The Google statement said: “What our users and partners are telling us is that they want Google search and Google applications on mobile, and we are working hard every day to deliver that.
