Are you connected to the right AP? Since I haven't messed with the sending code, it *SHOULD* work Do you receive any "SMS Push" notification? If not, the problem might be that your operator does not have your phone marked as "MMS Enabled". On the other hand, there are some bugs in receiving the "SMS Push" which I'm working on fixing, which might also be the problem. IMO, wait for a new release, if it still doesn't work, ask your service provider if they are sending your phone the MMS messages or not It would be possible yes, but making sure each contact does not have a phone number would be a bit expensive in processing power (at least in the way it's currently handled) - I think adding a searchbar would suffice, even though contacts without a number would show up?
