MMS not working after unlock.

[Leotno]

Hey all, I've looked and can't find a solution for my problem. I have a Iphone 4 on At&t. Version 4.0.1, baseband 1.59.

I have unlocked with ultrasn0w and now my MMS is not working. I uninstalled ultrasn0w and it seems to fix my problem, is there a way to unlock and still have my MMS working? Is there a step that I am missing? Yes, my MMS is turned on, in the settings menu.

You unlocked your phone and you are still using att??? You don't need to unlock to use them even as a gophone.

Probably because the TS like me, likes to travel internationally and use a local SIM when outside the US...

TS, MMS should work if you are w/ AT&T even w/ ultrasn0w installed... Do you have any push fixes installed or maybe you changed the APN?

That is correct. Every year or so I travel out of the US and use a local sim from which ever country I am in.

As far as settings, I have not changed any APN settings, well not intentionally. Nor do I have any push fixes.

I don't know if they fixed it but having ultrasnow installed and using an official carrier did that to everyone. If u remove it your mms will work again. Install it when u need to use a foreign simcard, it takes less than a minute.
