Yes, because like sms, this is a service provided by your service provider/telco. You however won't be charged for receiving but of course will be, for sending.

So I just today after having my girlfriend trying to send me a MMS and reminding me of that Iphone does not support MMS (go apple), discovered SwirlyMMS, I was stoked, went on cydia and downloaded it and everything went smooth till I clicked on getting demo license and there it was, one fail after another. after about 20 minutes I realized something that I think is what we all have been a victim of. when you are in Cydia and you search for swirlyMMS. Dont install the first one. that is the old version. scroll down till you see SwirlyMMS2. with a tiny 2 at the end. download and install that one and run it to buy your license. They dont offer a 2 week demo license anymore. thats why we have not been lucky. we have been using a version that is not supported any more.

I got mine to work perfectly for a cost of 12 bucks
