Horrible Service with the diamond

[parkman25]

So I have the Alltel Diamond, and recently, I just downloaded the new Juicy ROM. However, lately i've been getting some horrible service.
Also, the internet won't "locate".
For example, I try and go to a simple site like google, and it brings up an error saying: error! cannot locate remote server.

It's extremely frustrating because this phone is my work. I don't know if the service has anything to do with it or what?

Can somebody please help me out here?

thanks in advance
