Alright, Light Flow seems to get the notifications okay, but it doesn't always turn them off right away after entering the app you've been notified for... I.E., SMS. I turned the screen back off after viewing the message, and the LED still blinked. I re-entered the SMS app, and after that the blinking stopped when the sreen was off. Maybe just a quirk? If it keeps happening, I'll just set it to clear manually or with the screen on or pull down the notification bar.
Yep. That's works. Just got a few messages while typing this.
On a side note... MMS seems a little screwy on this port of JB. All MMS messages are in slideshow format, and some are randomly black and white. You can save the attachments, but they are of lower resolution than the original sent. Unless that's just native JB behavior?
I'll try it out with Handcent to see if it's just with stock messaging. Will report back later.
