Loving the product so far!
There is one immediate bug I have to report though, because its driving me nuts!
Whenever a program is executing the raw_input() function, the iPad speakers emit a continuous quiet whine. It's like the sound you get from speakers that are turned on but there's no input connected to them. It only happens when executing this function and it stops when you return to the editor, or if the function completes. It also stops if you switch apps, but it resumes again upon return. It happens with very simple programs which trigger no sound of their own, this repros it:
This whines until you hit return, is silent for 5 secs then starts whining again.
Also my iPad sound is muted and the volume is turned down, but still it happens. I have to stress, it is very quiet, you may have to literally hold the device's speaker to you ear to hear it.
Occurs with Pythonista 1.2:
Occurs on: iPad 2, iOS 6.0.1 (10a523)
Does not occur on: iPhone 4, iOS 5.1.1 (9b206)
I'm enjoying Pythonista very much, keep up the good work!
