Playstationmods have posted the following on their website which is otherwise closed:

"Due to recent legal proceedings by Sony towards our sale of the NEO4 chip we have decided to close down all our modchip operations indefinitely.
At the end of the day we work hard on our main games and repairs businesses and it is simply not worth jeopardizing our staffs futures just to do modchips. This is the first time we've been asked to stop supplying modchips by Sony and we will comply without reservation and without prejudice.

Our new online Console Spares & Repair / DVD Player / Games & Gadgets shops will be open in the new year.

Thank you for your support and we hope you have a Happy Christmas and a Prosperous New Year."
