Hey everyone I have a newb question. After upgrading to the new OS 4.6.1.231 on Tmobile I am getting a Yellow Globe icon. I got this before when I first got the phone but I forgot how to turn that notification off. Also how do I turn off the Facebook notification on my homescreen. I thought I went into the app and did it but I still getting notifications. Plus I read that there is an even newer OS is this true?
