It's not ready for everyone, but the Sony Ericsson Xperia X10 has just got confirmation of an Android Gingerbread update, along with some added Facebook functionality.That's not bad for a phone we reviewed in April 2010, making it positively ancient in mobile phone terms. Not so now though, with Android 2.3.3 added to the X10, along with Facebook Inside Xperia, the latter meaning deep Facebook integration. We outlined this back in May if you want the lowdown. The update will offer features such as the ability to use your phone as a Wi-Fi hotspot, an improved music player with equaliser, USB tethering, a new photo widget and the option to arrange your apps in just the way you want them.That's the good news, Now the not-so-good bit. According to Android Central, you'll need an unbranded/SIM-free version of an X10 to get it initially. So if you are on a network contract, forget it for a while. The networks will want to test it for stability and security, so expect maybe a month or so wait, depending on their workloads. In fact, you'll have to wait even if you have a SIM-free phone. The update isn't quite ready yet. You'll need to wait a few more days as things are fine-tuned. Keep checking in other words, but expect it any day now.
