The Latest OS threads are kept at the top of this (and every model line) subforum. They not only contain the latest OS for your model but detailed instructions and discussions regarding the particular OS release (fixes, issues, etc).
I still don't know which OS I should down load. There are so many different ones and that is why I am asking you which one should I download. THere is 5.0, 4.7 etc. Can I get some direction on that at least?
