Does Anyone Know If Planet Computers Is Still in Business?

Several years ago I bought a Planet Computers Gemini phone (imagine an old Psion Revo with a 4G modem.) I was wanting to get their latest model, but the store page says they're back-ordered until August 23rd (this post is being written on September 18th). Emails to their main email address bounce.

Just curious if anyone on HN knows someone who knows someone who knows these guys. I would love to buy another one of their phones, but obviously would prefer to verify they're still in business before giving them my credit card number.

Their main page is still up as of 2023-09-18: https://www.www3.planetcom.co.uk/
