Hello! I have a Samsung Galaxy Pop/Mini, and I upgraded it from 2.2 something to 2.3.6 a few months ago, and I tried using its 3G very recently, and wasn't able to for some reason. It always said, Data Network Mode Deactivated no matter how much I tried long-pressing the power button and toggling it. Please help! The APN and stuff I got from the service provider's message and stuff, still no luck. The Data Icon doesn't ever show up.
