While we’ve already seen the Xperia X8 here in the UK, Sony Ericsson have just announced that the “medium sized X10” is now shipping worldwide. However comments from Rikard Skogberg indicate that although the handset is now shipping, not all markets or networks will release the handset immediately. It was hinted at that some markets may wait to release the Android powered handset until the 2.1 update is released for it. We already know Android 2.1 has been delayed for the Xperia X10 range. Unfortunately the Android 2.1 update will be released slightly later for the X8.
Another factor in when the handset is released in your market, is network availability. It’s unknown what US carriers will carry the handset when it’s released in the US, which will play a part in the release schedule for the Xperia X8.
