Well.. I lost my USB/phone computer cable, and I'm away on vacation. Just wondering, if the OTA comes out before I get home and am able to back up on my computer, should I upgrade? or should i always backup my phone before updating, whether OTA or via DM?
I recommend backing up first, just on the outside chance something goes wrong. Especially with OTA, poor signal or something like that could mess up the download.
You should be able to buy a USB cable for about $15 - $20.
