A few thing I have learned about the dcdcarrier cabs for Alltel. I am told the 2008 one is better than the newest 20091031 cab. The newest one converts your Ev into Ra, but most ROMs don't supports Ra icons in the taskbar so then it screws stuff up there anyways.

To get your "My location" working try this:

Install the PPST cab and run PPST.exe
Update your PRL
Install the dcd 2008 cab
Look for a cab called "GPS Registry - Alltel"
And most importantly, turn off TF3D and delete the "forecast_cache" file from /Application Data/HTC/databases then turn TF3D back on and try again.

If that doesn't fix it then it may just not work for Alltel phones, which seems to be an issue with some of the ROMs around...
