Anyone having delayed text message issues?

[krnfrk6663]

I'm not talking about the ones where they're a few minutes apart, I'm talking more like 20-30, sometimes and hour off, I get them all at once, or I get them scattered out of order. Different people each time. I've been back and forth with Sprint about this and I'm getting no where with them. Any ideas from the great minds here? I text more then I talk most of the time, so it's becoming an issue anymore. I've been having slight issue since I've got the phone, but it's seeming to get worse. No, I'm not roaming when this happens. When I do roam it seems to get my texts to me at least in order. Any insight will be appreiciated.
