It looks like Apple has now managed to catch up with the demand for its new iPhone X in both the US and the UK.
The last time we checked the new iPhone would ship within a couple of days, this has now changed in both the US and UK Apple stores online.
If you order the new iPhone in the UK or US stores you can now have the handset delivered the next day. If you buy it to pickup at an Apple store you can now pick it up on the same day.
It was expected to take Apple until early January to catch up with demand for the handset, it looks like they have now managed to catch up. We heard recently that improved production had helped Apple improve their shipping times.
