Hello Forum, here's my story and situation, if anyone could help that would be great. Thanks in advance. I have the AT&T HTC Aria, it's running 2.1-update1. I've rooted using Unrevoked3, Superuser works. I can get su in the terminal emulator. I'm still running the stock ROM. The phone also still seems to be S-ON even though it is rooted. My issue is that Titanium Backup says that I need to allow applications from Unknown Sources in order to use it. I want to use it so that I can make a backup and flash a custom ROM. My Aria does not have that option. Is there anything I can do?
