iPhone 3G - Why are all my Text Messages Delayed!!!

Im getting text messaging delays.
Iv been getting these delays and it hasn't been fixed since when I bought my Iphone.

When I called the guy said that these delays happen to everyone and its normal.

Now I realized that this cant be normal. I get hourly delays sometimes and it really messes with peoples mind.
If my texts are delayed by hours it beats the purpose of sending a quick message.

What should I do how do I fix it ?

check this out, storego.com, might get a replacement, hope this helps.
