This is the response I received from straight talk management....I responded and said that wasn't true because if you turn off cellular data the problem of delayed msgs stops immediately. I would like to think apple would like to pipe in here....
Dear Scott:
Thank you for your interest in Straight Talk Wireless. We are responding
to your recent inquiry.
We have looked further into this matter. We have as well verified the
link you've sent us. We would like you to know that the delay thats
happening to the iMessage service is related to Apple's servers. Like
Blackberry's BBM (Blackberry Messenger), these services are totally
powered by the manufacturer, in this case Apple. Due to the fact that it
works through the Internet, this service depends completely on their
internal network.
If you have any further questions or concerns, please contact one of our
customer care representatives at 1-800-876-5753. For your convenience,
our representatives are available Monday-Sunday from 8:00 AM to 10:00 PM
EST.
Thank you for being a Straight Talk Wireless customer. We appreciate
your business.
Sincerely,
Straight Talk Wireless

I need for someone to acknowledge this problem an address it. I have
called tech support numerous times and repeatedly been told everything
is normal. You can begin by reading this thread rather then me explain
it you can read all about everyone else who has the same exact problem.
I'd like to stick with straighttalk but I can't unless you can fix this.
