simple, i do this myself. This way the screen will light up when the message comes, if you dont have it setup right you will not see the phone light up when the message comes.
Go into lockinfo and set it to block all pop ups.
Now go to bitesms and in the settings set it to use Apple alert in lockscreen mode.
How i have it now is that the new message will pop up in lockinfo...if you set lockinfo to use bitesms for tap fuction. When the message pops up, you tap the message in lockinfo and bitesms quick reply window will pop up.
Now there are a couple caveats with this. A- You cant see when people send you pictures. Even if there is a text message with it, it will show up on lock screen as "No Message" and B- when you want to reply to a text, you need to tap the message and open up the window and tap reply to get to the keyboard to enter your message.
Let me know if you need any help with this.
