Why not just use APN? It's far easier than calling AT&T. It only takes about 5 seconds to do. Also, AT&T could remote the WIX block at any time and you wouldn't know.
I'm not sure how you are changing your APN but it's a simple one time process. All you do is go to http://unlockit.co.nz/ on your iphone and install the profile.
I highly recommend you do this even if you are getting a WIX block.
I'm using that exact same APN changer you mention above on the 3G. AT&T still sent that text message today though, saying I had 'til Sept. 13th or something to settle up since they discovered I was using an iPhone without a data plan.
So even WITH that APN changer that I've used on both the original iPhone and the iPhone 3G, AT&T still figured it out.
I'm hoping the combination of BOTH the APN Changer *and* calling AT&T to disable data will do the trick.
Or it's back to a RAZR, which won't be fun for the spouse...I don't know what else to do.
Changing methods will not stop AT&T from finding out. As soon as you put the SIM back in the iPhone, they will know you have an iPhone. Yes, they may send txt messages about not having a data plan - however in my experience and from what I have read about on the web, they will not actually do it.
EDIT: Yes, i've heard that they are now putting deadlines on people. This is new to me, so they may very well be cracking down. I have not received the txt yet but am keeping well aware.
Unless somebody figures out how to change the IMEI number (which hasn't been since the old 1.x firmware and even then it wasn't a "real" change; not to mention it's highly illegal), there's no way around it.
Just ignore any texts and u should be good. If they add it in call and cancell it while your sim is in a noniphone cell.
And then tell her to stop using it. I think it's just scare tacticts by At&t. They won't do squat.
That is the most ridiculous thing I have ever heard in my life. AT&T will *NOT* charge an ETF for not having a data plan.
Honestly, where do you people think such stupid s*** up?
I just received the text to call 611 about the data plan too, after you switched the sim to the razr and called att did you mention that you received the text regarding the iphone?
