I don't understand internet flakiness on the iphone

[solinari6]

Ok, so with my old iphone, I was used to getting errors trying to access the internet every now and then, when the cell phone signal was low. (the actual error is: Safari could not open the page because the server stopped responding)

but now with the 3g iphone, i'm getting these errors seemingly randomly. Sometimes it can't connect to the internet when I have 4 bars of signal, but sometimes it CAN connect when it actually says "NO SERVICE". So I really don't understand what is causing these problems. Anyone know?

Although I haven't noticed it for "No Service", unless I'm on WiFi, I have noticed Safari not working properly despite having a few bars of service. It seems to have gotten better with 2.0.2, but when in doubt, hold for 8 seconds...
