I have a 2G iPhone with 3.0 on prepay T-Mobile. I bought Swirlymms2. I thought I saw when it was installing, it was making itself the default app, but I sent a text and received a response, which came to the iPhone messages app. How do I make Swirly the default? One more question if I may, which settings do I use in Swirly? There's four choices, but I am unsure which to use or if it matters. Thanks for any help.
