Help with connection on and off

[audiofreak]

I am on 3.1.2 jailbroken and every once and a while I totally loose connection and the status bar reads No Service. It lasts about 5 seconds then automatically reconnects.

I'll have full 3G coverage when this happens so thats not an issue.
I have reset my network settings and that does not work.
I have restored and even when unjailbroken it still happens.

It occurs most often when I am tethering and have multiple tabs open, almost as if it over loads and cuts my connection?

Any ideas?

If it happens when unjailbroken then it's probly what you thought... network overload. Sometimes when I'm downloading on 3G it will kick me off onto Edge. Does this happen in multiple locations?
