Thank you for contacting the Sony Ericsson Contact Center. With regards to your query, We have communicated to our operators, business partners and distributors that some volumes of Xperia Arc and Neo phones have been affected by the situation in Japan. However, due to supply chain disruptions resulting from this situation in Japan, we have shifted the launch of Xperia Neo and Arc for early Q4 (July) in the African region. Should you require any further assistance, please feel free to contact us again. For more information on our products and services, please feel free to visit our website.
