Came across an interesting bug today, only happened once so I can't tell if it was an isolated incident.
I had a couple loops down, and when i hit save and then touched to fill in the text to name the set, at that exact moment I recieved a text message. What was wierd was that i could see the text preview bubble behind the on screen keyboard, but i couldn't get rid of the keyboard or click the "reply" or "close" button on the text bubbles. I had no other choice but to reset my phone.
Not a big deal, just thought I would mention it. I mean really the chances of this happening often are pretty rare...
