Hi guys, I'm new to the site and need some advice on ordering DIRECTV service. I'm primarily ordering it so that I can take advantage of the new Unlimited Data plan offer for AT&T + DIRECTV subscribers. I'm on the old unlimited data plan, but my wife isn't. A couple of things are not clear to me and hoping you can help me clear those out: 1. Can I order DIRECTV service and then decide to jump on the unlimited data plan after I'm satisfied with the installation? My line is on the old unlimited data plan, and I don't want to switch out of that until I'm sure service is going to work fine at my home. The last thing I want is to have AT&T switch me out to unlimited only to find out there's a problem with my home and then not be able to go back to my previous plan. 2. Is there any difference if I order service from the DIRECTV site/phone vs. AT&T site/phone? I have an email offer from AT&T where they offer a $200 Visa card with new service, but it's not clear to me whether I can get that deal if I order from the DIRECTV site. It appears the sites operate separately at the moment. It's also not clear to me whether I can get the referral bonus using my friend's account # if I go through AT&T. I want to make sure I can still do the AT&T unlimited plan even if order through DIRECTV. 3. Does anyone have any experience ordering via http://cw.directv.com/DTVAPP/?I've read people have had bad experiences with installations when ordering in a Costco store as they use a 3rd party company for the installs. This website appears to be the same DIRECTV site, and you can still get the $300 Costco gift card. If I can get the gift card plus get the AT&T benefits (2-year price lock + have access to unlimited plan), this would be the best deal, but don't want the hassle of dealing with a crappy installation company. Thanks in advance for the help.
