You may have noticed that on 11/28/2011, Sony Ericsson mistakenly posted a promo offering Xperia owners 50GB free storage via the Box for Android mobile app. This offer is not active. We are committed to delivering the best Box mobile experience to all our Android customers, and apologize profusely for any misunderstanding.

Sony Ericsson 在网页公布，跟云端储存商 Box.net 合作，为 Xperia 手机用家提供 50GB 云端储存空间。
要享用这个 50GB 储存空间，只需在 Android Market 下载安装 Box App，并利用 Sony Ericsson Xperia 手机在 2012年12月31日前 登入 Box.net，你就会获得 50GB 免费云端储存空间。
Xperia™ exclusive – Get 50 GB free cloud storage for life
Until December 31st 2012, Xperia™ owners can get an exclusive offer of 50GB (yes 50, not 5) free storage in Box.net’s cloud. Store, retrieve and edit files from any device, with only one copy in the cloud. Box.net specializes in synchronizing their services across different devices. Brilliant, we think.Simply log in to your Box.net account from any Sony Ericsson Xperia Android handset before December 31st 2012. That’s it. Once you have done that you have 50GB free cloud storage on your account for life.
Sony Ericsson 文中未有表明这项服务是否限定某地区用家，还是全球 Xperia 用家也适用，我们当然希望所有 Xperia 用家也可享用呢！
