I have the 64 GB N9 and everything is working perfect except opening MMS messages. My service is with at&t but i don't think its a carrier issue as the phone was working fine previously.

When I receive an MMS message and attempt click on it, the messaging application simply just closes. The only way to accept any more message from the person who sends me the MMS message, is to delete the conversation. I cannot pin point when this all began, but I am wondering is this has been happening since I install and used N9 QTweak. Let me know if anyone can assist in solving this problem as I am trying my best not to do a reset.

Thx,
