I'm writing an app that stores secret (encrypted+hidden using steg) information in MMS messages. Obviously I need a way to test this, in particular, sending and receiving MMS messages. I have one Android phone, a Nexus One. I know that MMS's cannot be sent between emulator instances, but other than using up loads of MMS credit, is there another way of testing out MMS sending/receiving without just spending loads of money?
Twilio just announced MMS support, and their marketing page has a test box to receive an MMS, could be useful for testing: http://www.twilio.com/mms
