http://forums.androidcentral.com – Keis isn't showing the update for my phone. Every time I connect my phone and open Keis it shows nothing under firmware not even the current version of my phone. That section is blank. I've un installed 2x and reinstalled but nothing. Most of the time I can't even get Keis to open on my computer. I want the jb update.... Help please.
