http://androidforums.com – I've had my galaxy ace for a few months and decided to root it. I used unlock root and it appeard to work as i get the options when booting with home key and pwer key at the the same time. My phone turns on but it now does not get a data connection! I also did things backwards because i downloaded titanium after this and although i can see it in app manager i can't find the icon to use. Are these related? I've tried un-rooting but that didnt work. Does anyone know if I have an easy fix to this? Thanks for any help. (General)
