Perhaps I can help a little - this was a big problem for me ever since I got the TP - never had the problem with my prior Mogul. I get a lot of texts, and they started rolling in all throughout the night, even though they were sent in the afternoon. Some I received instaneously - others delayed by up to 12 hours.

Called Sprint Tech Support - first person just had the same "network outage" excuse, gave me a $60 credit, and refused to do anything else.

Called right back, demanded to go to the next level of Tech Support (level 2?) - finally got someone that actually wanted to help - and said the network outage was BS and has nothing to do with text messaging (!). Spent 2.5 hours on the phone with them. While they couldn't help me at first, they then went to their supervisor (level 3?) - and they had the solution that even this person hadn't heard of. He immediately knew the problem - said there was basically a "text message clog" in my routing, and they have a command that runs a "text message plunger" (I couldn't make this up if I tried) through the routing to my phone. Immediately worked - text messages became instantaneous and no further problems - old text messages came in right away as well - success!

I can also tell you the following did NOT work that tech support tried:

1. Changing the routing number on the phone
2. Resetting the phone
3. Turning off and then turning on SMS's on Sprint's side
4. Re-entering in account and plan information and/or resetting plan
5. Updating the profile

Unfortunately they didn't really give me the technical details - but I think if you consistently have this problem, you need to work your way up the tech support chain to get some of the uber-knowledgeable people.
