Frequently lose data connection

[2000man]

I am on my 2nd 800w. I have Dashwire (on manual sync), weather panel, soft reset, kinoma, opera and that's is about it. I keep losing data connection and cannot use the internet or check mail. I have to soft reset or turn the phone on and off. This is really annoying. You don't know that your phone isn't checking for new emails until you go the mail screen and see an error displayed. Is there something wrong with my phone or is it the software?
