Fixing a fried 3g radio

[cornellfOo]

I have an AT&T Tilt that's suffering from the broken 3G radio defect and I was wondering if there's a way to fix it on my own. It's now out of warranty so HTC is asking for a lot of $$$ to fix it.

Is there any DIY solution to fixing it? Is there a part I can replace or something like that?

Thanks for your help.... :)

I might be interested in the damaged phone if you decide to part with it...
