Flutter, from Juice Wireless, at first glance seemed like it might do the trick. Flutter claims to send MMS and your geo-tagged location from your iPhone to another mobile phone.
The problem is that the recipient can only see the picture messages by going to JuiceCaster's Web site. In that sense, it's not at all MMS at all.
Consequently, it's hard to find any reason that you might use Flutter instead of email because it doesn't offer any significant advantages.
