Root Unrooting question

[chaos32]

So im unrooting because tomorrow I'm taking my phone back to verizon to get a refurb. (my track ball stopped working)

FIRST
Do I even need to unroot or will they even check/notice??

SECOND
I'm reading this post
[ROM][10/20/2010]FlashBack21 v1 -Return to Factory Stock - UPDATED - xda-developers
what is the diff between radio and not radio....i dont even know what that means?


Thanks for the help in advance!

I'd definitely use Flashback21. The radio replaces the radio software - you know, the driver that controls how the handset communicates with cell towers, WiFi, and I think Bluetooth - with the version that was in the July over the air update. I'd say there is no good reason to install the radio version for the purposes you describe.

I doubt that Verizon even checks, but, in case yours is the one that they do check, I'd still want it unrooted.

Just use the one without radio, but it doesn't really matter.
