Just a quick tech note, installed Text Plus the other day, thinking that I might be able to use it to text with my little sister who lives in another country. A few days later noticed that my ringer wasn't working properly. Turns out that when I plugged in a set of headphones it disabled the speaker (like it was supposed to) but then when I unplugged them it didn't restore them to operation. This morning I uninstalled the last six or so apps I added, one at a time, and when I took Text Plus off, bingo, speakers are working again.
Just so you know.
