I couldn't get anything to work. I tried evey rom and both radios....
I used the same trick on my old mogul. Here's what I did. I never installed gpsviewer. Instead I used a program called AstroGPSLauncher. This program will prime the gps for you. I then used the sksmgrwm5.cab and created a new shot cut for iGO. So now all I have to do is launch this one Icon and iGO launches and sat lock hits in under 5 sec. This has worked with both radios and I am using Ghetto' snew rom kitchen.
I cannot remember where I found these things the first time. I believe it was on the
www.xda-developers.com. It was under the titan threads. If I can find the exact link I will post them here.
I hope this helps.. I am really tired so I hopes this makes sense. I can help more if anyone needs it.
Good Luck. I also have the program cabs I can post. I just have to figure out how to go that.
EDITED:
Here is the original link at XDA. It contails all the cabs and links you need. It should work. Mine works perfectly now everytime... http://forum.xda-developers.com/showthread.php?t=364199
