Okay so, I was bored & decided I would make a backup of my phone, & then restore my very first(stock) backup. So I did that & checked for updates & got "A software update 2.3.340.en US (25.7 MB) is available for download".
I'm new to the whole smartphone thing, so my question is should I update? The backup of my phone before restoring to stock is running rubix 1.9. Would I still be able to use that if I updated?
