Every time I try to install an app I got on this website it tells me "For Security, your phone is set to block installation of applications not sourced in the Android Market" How do I unblock it?

[Hook/\hzorr]

Goto settings & Click applications and check the unknown sources option.

The only options I have are "Manage Applications", "Running Services", "Development", and "USB settings". And in each of those I can't find that.

Is it from at&t?

Yes

At&t is fucked up they take that option out of their android phones only way to get it is to root it and install a custom rom for your phone

That sucks. Do you know what that rom is called?

[bloop]

Not a clue I don't have your phone
