In theory yes it should be easy but it never is usually. My experience saw me watch it freeze three times, uninstall it, re-install it, freeze again, finally worked after being frozen during the update for about twenty minutes. Kies is pure dogcrap , plainly put and pardon my bluntness. I really don't see why it couldn't be an OTA when it would've went down easier for people. Most of the ones who care will get it but what about those who don't read sites like this getting it. AT&T finally gave the update but STILL screwed over their customers. I can't wait till my contract is up tbh. I'll get Straight Talk and a Nexus cause this is for the birds. lol Watch it take five months or more if we even get 4.2.
