I have an unlocked Nokia E71, but my understanding is that ANY GSM phone will do, as long as it works on AT&T. You can buy a cheap Nokia pay-as-you-go phone for about $10 that will work. You need to pull the SIM card from your iPhone and plug it into the non-iPhone. Wait some time, make a couple test phone calls to ensure it's working.

AT&T knows what phone you're using (model wise) and will allow or block certain services appropriately (such as MMS messaging). The hacked carrier profile which enables tethering and MMS also disables the model reporting agent, so the iPhone no longer updates AT&T as to what model of phone it is.

The idea is that by using the non-iPhone, AT&T will update what it thinks you are using to be a non-iPhone. At that point, you can then plug the SIM back into the iPhone and your MMS messages will go through. How do you know what that point in time is? Since my non-iPhone supports MMS as well, I kept trying to send an MMS until it went through. That's when you know.

And now my iPhone tethers, does MMS, and my Visual Voicemail works.

Thanks for the VVM tip!

Whch version of the carrier file will stop reporting which phone you have back to att and where can we get it?

UPDATE: I did this again except with an unlocked nokia. Did the SIM swap stuff. Previously I did this using an att fuze with no success. Now it is working. I have been sending MMS's for the past 45 minutes. Hope it sticks. I currently have the at&t 5.0 carrier file. I also never rebooted my phone. I just did the swap while the phone was on. I have heard of some people having it stop working after a re-boot. Not sure how true this is or not. Also, is there a carrier file that is out there that will NOT tell at&t you have the iphone again..? Or atleast not allow the mms to be blocked again..? Thanks guys! Now watch, they will make MMS offical for at&t tomorrow! LOL
