I got an email because I registered my Olympus camera online after I bought it. The email indicated that new firmware was available for the SP-350. I could move to the 1.3 version which included some fixes for battery-use indication.
I had never even unsealed the manufacturer's CDROM as I am perfectly happy organizing my photos using the native options in Windows XP. If I wanted to upgrade my camera, however, it instructed I had to do so via the Olympus Master software. I loaded it and and found that even it had a newer version available. I got that up-to-date first.
Next, I followed the instructions and connected the camera to a USB port. It recognized that my current version was only 1.1 and offered to download 1.3 from the Internet. I let it. When it was actually transferring from my hard disk to the camera, there was a nice graphic which showed on the LCD. After two minutes, it simply read, OK. I unplugged everything and turned off the camera. Although I've been carrying it around for eight months now, it's basically brand-new now.
I wonder what version my toaster is running?
