Need to let people know where you are but can't answer the phone? Then this handy app could be just the thing for you. I went to see Shrek 3 the other night, it's not so good, and as always I had to turn my phone off.
However with Ignore with SMS all you need to do to let friends know where you are is pre-set the text message you want to send out - I'm watching Shrek 3, it's terrible, for example - then keep your mobile on silent.
As soon as a call comes in just press the assigned button and the message gets sent. There are other uses of course if you want to ignore someone on purpose but let's not go into that.
