    I've noticed that after I install a custom ROM, my 3G speed dropped from .73 Mbps to .47Mbps. I know it's not that big of a difference, but I just wanna know if this is in fact confirmed.

    Flashing a custom ROM shouldn't affect 3G unless you flashed an different radio file.

    For example, if you have a Nexus One and you want to have CyanogenMod 5.0.8, it requires you to flash the Froyo radio. Remember though, flashing radios is dangerous and you shouldn't unless you have to or have problems as it can caused bricked phones if you do it incorrectly.

    Have you flashed a new radio? What ROM did you flash?

    Why would flashing new radio load cause a phone to become bricked? Does it do something to the startup sequence that causes the phone to not be able to boot up (not sure why it would do that)?

    It seems like a bad radio image would just stop the wifi and cell phone functionality to not work, but it should still be able to boot up - and should still be able wipe and reload through the usb port...

    I must be missing something.

    We've all flashed our radios a few times doing the ERE27 OTA update & FRF85B OTA update, flashing a radio in itself isn't inherently dangerous, but if something should go wrong during the flash, then the phone would be bricked.

    Correct. So you should be careful is all I was saying Schwin97.

    If you're on FroYo, you need to have the FroYo radio.

    I recommend going through here: Nexus One - xda-developers

    Also, some kernels with undervolting *CAN* affect signal. Be aware.
