I can't remember when I first downloaded SwirlyMMS but I think it was almost two years ago. Until last week I was still using it on my 1.1.2 iPhone with a PrePaid T-Mobile plan that costs me $0.05 per received SMS/MMS. When I originally downloaded SwirlyMMS it worked perfectly but if I went to my inbox it would then download all my messages. This was the expected behavior but it would cost me a bundle each time I accidentally downloaded my messages (I don't care about their content, I just care to know I have them). After a while it quit working and would only download the headers. My phone would still vibrate or ring when I received an MMS. This was perfect for me since it meant I got unlimited MMS alerts without having to pay for them (I couldn't read them, but like I said I don't care to actually read them).
Last week I decided to finally upgrade to 3.1.2. I'm prepared to buy a license but I want to make sure the behavior is still the same. Since there is no longer a free trial I have no way to find out. Is it possible to only have SwirlyMMS2 download the headers? Fetching the entire message in the background would be completely unacceptable for my use.
