Q: I think we may have goofed. We bought a tablet that claims to be 'Wi-Fi only.' Can it be activated to handle 4G cellular data?
问：我觉得我们可能迷糊了。我们买了一部据称“只能连接Wi-Fi”的平板电脑。这部设备能否用来接收4G蜂窝数据？
A: It's highly unlikely. To use cellular data, a tablet needs extra chips, antennas, and other hardware and software, similar to what a smartphone includes. If it says 'Wi-Fi only,' that very likely means it lacks this hardware.
答：相当不可能。要接收蜂窝数据的话，一部平板电脑必须配备额外的芯片、天线以及其他硬件软件，配置就像智能手机那样。如果该设备标明了“只能连接Wi-Fi”，那么极有可能意味着缺少这种硬件。
In fact, if you compare the specs on, say, an iPad, or a Google Nexus 7 tablet, you'll see that, not only are the prices higher for the 4G cellular versions, but they weigh slightly more, to accommodate the cellular gear.
实际上，你可以看看iPad、谷歌(Google) Nexus 7等平板电脑的说明书，就会发现4G版本设备不仅价格更贵，而且也略微重一些，这就是因为需要配置蜂窝设备。
Q: I am trying to monitor my teenagers' iPhones. I bought an app called PhoneSheriff based upon good reviews. However when I went to install it, it says to ensure the targeted iPhone is 'Jailbroken.' I believe this will void the Apple warranties. Is there anything I can do to monitor my teenagers' iPhones without jailbreaking?
问：我正尝试着监控我家小孩的iPhone。因为评价不错，我购买了一款名为“PhoneSheriff”的应用，但安装的时候，系统提示称要确保目标iPhone已经“越狱”了。我认为越狱的话会使苹果授权失效。有没有什么不必越狱就能监控我家小孩手机的办法？
A: There's an app called TeenSafe that claims to be the only monitoring system for iPhones that doesn't require that the target phone be jailbroken, which essentially means hacking the phone to accept apps that Apple hasn't approved.
答：有一款名为“TeenSafe”的应用，据说是唯一一款不要求目标手机越狱的iPhone监控软件；越狱实际上意为黑入手机以安装未经苹果批准的软件。
It apparently works via the Web and relies on your knowing your children's Apple IDs and passwords (presumably, even if they change). I haven't tested or reviewed the app, so I can't recommend it.
该软件似乎是通过网络运行的，但首先你必须知道你家孩子的苹果ID和密码。我还没有测评过该款应用，因此我没法推荐。
