I recently read that Uplink was available from Software Centre. But I go to the "For purchase" section of the software centre and there are only 7 entries. There's no trace of Uplink (or Darwinia). I'm running 32-bit natty and have refreshed my software sources, installed all updates, etc. Is this app not available because I live in Australia? Is there any way to make it appear so i can spend my $$?
