Help decide DSLR cameras? Any appropriate opinion very much appreciated?

So just yesterday, I got the Canon Rebel T3 / 1100D from best buy.
I got it for about $550 (including tax) which I think is a pretty good deal.

I love the camera but, as a beginner, I obviously struggle with some functions. Like i don't know how to turn off flash when it's on auto or portrait mode etc even when I read the manual (if you can tell me how. It's be highly appreciated.

What I really want to know is whether I should keep it or not.
I don't plan on going in depth into photography but I love taking pictures.
I really really wanted a variangles DSLR but they were expensive (nikons are cheaper but their lens are incredibly expensive so I avoided Nikon)

SO. Do you think in the near future, there will be more variangled DSLRs & should I return my T3 to wait for more variangled DSLRs to come out preferably under the price of $600?

This is the perfect camera for you since you're a beginner. Don't bother a camera just for the flippy-screen thing - you should be using the viewfinder. Spend some time 1) reading your manual 2) at your local library reading the basic photography books they have. Learn how to use your camera in full-manual, learn how shutter speed/aperture/ISO relate to one-another, etc etc etc.

First what is "variangled"? Are you talking about the view screen?

The t3 is an excellent camera for stills and video especially for a beginner like you. If you're serious about photography and really want to learn how to control a dslr this would be an excellent tool on which to get that training.

Flash in auto is hard wired into the camera and can't be turned off. For that go to "P" = program.
It is basically a full auto setting except for flash. In this setting you'll have to physically open the
flash to use it.

Another point you may find valuable. I own two Canon dslr bodies, the XS and the 500D (t1i) I have them both set to use a single focal point. This can't be done in full auto but can be set to work in
all manual settings. It works much better than the multi point because it wants to always grab the
closest object to the camera.

With this in mind say you're shooting a group of people but you want to focus on a particular person in that group. Multi focus won't do that, especially if that person is at the back of the group as they are positioned relative to the camera. With single point you can do that… Just a thought. It's the only way I shoot, never full auto only in program or one of the manual settings.

If you're serious learn all you can now because a more expensive camera won't improve your photography… All you'll do is spend more money for the same results you're getting now - doesn't make much sense to me.
