Would sending MMS not be the biggest priority? Most telco send a txt msg with a link to a web page where an MMS picture can be viewed/downloaded. This is a simple task on a phone with a high quality browser such as the N900.

However on a dumb phone with little or no browser viewing an email isnt possible whereas MMS msgs work well. So would the main use case for MMS msgs not be sending pictures to dumb phones or people who dont check email/social networking sites often/not at all?

Just my 2c.
