I hope it's in 3.1, any devs have any timeline idea as to when they'll drop 3.1 finally?
No one knows for sure, but based on history it will probably be in late August / early September.
Or earlier...
I voted no simply because I have lost a lot of faith in AT&T .. lol
MMS has been in the basic packaging for a long time. AT&T optted-out! iphone users eat up on average 400mb a month per user and seeing how AT&T is the only U.S carrier for iPhone you can imagine the fall out if they pushed in MMS and tethering. AT&T doesn't have the BW for it hence the network upgrades. MMS will more than likely come in Sept but AT&T will likely put a cap or limit to the amount since they are not going to charge a separate fee for MMS.
