Thanks this does a good job for the popup but now I receive no sounds for a new message even when I have sounds enabled...
Same here, if you find a fix let me know. I haven't looked for one yet.
This is what I have found:
The way is seems to work is by stopping the New Mail "Ringtone" and playing a sound file. This means that the volume of the notification is not the same as your ringer volume but the sound (Music & game sound effects) volume.
So my game volume was turned all the way down. I have turned it up and now it works. Hopefully the developer can find another workaround for this.
get lockinfo. you will here the sound when you get a new email, and can read teh email from teh lockscreen. and can delete from there if needed or open your mail app to reply or what not.
Yeah but Lockinfo cost 4 times more, 8 clams :\
