We’ve provided information on how to root the Xperia handsets here before and in the past rooting has always been for a positive reason. The main reason for rooting is that it allows you to remove preinstalled apps, either installed by Sony Ericsson such as Timescape, or network specific apps such as Vodafone’s 360 application. There are of course other positive reasons to root your handset and with Google Android being a pretty open OS, rooting hasn’t been much of a problem. That may change soon however.

In general, phones that have slide out parts, like the recently released Xperia Play and the Xperia X10 Mini Pro that was released last year, are harder to find cases for than the regular “candybar” styled phone, whether it has a touch screen or not. Last year we saw many cases for the Xperia X10 and X10 Mini Pro, many of which allowed you to change the look of your phone but, also protect it. The X10 Mini Pro however didn’t have as many cases on the market and still hasn’t.

When Sony Ericsson announced that they had changed their plans for the Xperia X10 and that it would not be stuck on Android 2.1 but, would instead be upgraded to Android 2.3 during the end of Q2/start of Q3, this pleased many customers. However it still left some of Sony Ericsson’s customers rather angry, as while this was great news for owners of the Xperia X10, it was also announced that the X10 Mini, X10 Mini Pro and Xperia X8 were not part of these plans and would remain on Android 2.1 as previously stated.

It appears that the Android Market has been updated on Xperia handsets which adds a link to Sony Ericsson apps. The update doesn’t actually appear to be a market update however, as there wasn’t a notification and uninstalling any Market updates, does not revert the Market to how it was.

While the Xperia Arc has been highly praised for it’s camera capabilities, especially in low light conditions, there is one aspect of the phone’s camera that doesn’t quite live up to the hype of the phone’s camera capabilities. It’s been noted over the weekend that while using the camera, if you want to zoom in on your subject, this is only possible if you change the camera settings to use the 2 megapixel camera mode. Sony Ericsson UK have said on Twitter that the solution would be to either use the camera in it’s 2 megapixel mode and use zoom, or use the camera in it’s full 8 megapixel capability but, zoom and crop the photo after taking it.
