Does a home pc still show up on facebook with iphones?

My twin brother knows when I'm on fb when I'm using my cell phone or laptop. If I use the home pc, will he know? I'm trying to plan a surprise and this iphone stuff is screwing it up.

Yup, he will know, because the settings that are on fb that are supposed to show you as being offline when you set them to that are fake, so no matter what device you fb from anyone can see you as online if they wanted to check on you, switching you're fb chat settings to offline don't work at all and the only way to not be detected is to not be active on Facebook.

  • Why won't the facebook icon on my iphone show up? I downloaded facebook on my iphone 4s, it says "installed" and everything, but an app icon never appeared for it. When i go to the app store, next to the facebook app it just says "OPEN" so i can't re-install it and the only place i can access it. Can someone tell me how to make the icon show up please?
  • Why won't facebook show the EDITED version of photos from my iphone? I upload all of my photos from my iPhone to Facebook. I always edit my photos (crop, lighting and red-eye) using the regular iPhone photo editor that comes standard in the photo application. When I upload the edited photos to Facebook, the originals ALWAYS show up. It is infuriating and I want to know what I'm doing wrong. I've tried everything but can't seem to fix the glitch.
  • Why does my iphone's screen not show but it still functions? I have a 3gs that still receives calls and functions with touch and calls and all, but the screen is blank. If i hold the home and power button together for a while, the Apple logo shows up for a quick second and the screen goes blank and the phone restarts (still functions after the reboot but screen is blank).So I don't know what the problem could be as the screen works perfectly when showing the apple logo, so now I'm confused. Somebody please help me
