Alright, I was able to find that out. Thanks!!! My OS is v4.3.0127, is it too old that I need a better version or I should keep it like that?
Take a step back for a second. The person who suggested you upgrade has
an 8310 while you have an 8330.
It made sense for him to upgrade, for you not so much. There are a few
enhancements but most of what 4.5 can do 4.3 can also.
Better idea would be get familiar with the device and OS you currently have,
and when comfortable do the upgrade. No one here or anywhere else should
try talking you into doing something you may not have the skill or
understanding to do.
