Take a look at this thread over at ppchaven.com. If you let the custumizations run then you have in effect locked the GPS function. I would also recommend flashing NFSFAN's 1.12 Verizon ROM. I never let the customizations run on my phone & had some GPS fuctionality without any fixes or hacks. Now after flashing NFSFAN's ROM the GPS works flawlessly with TomTom. I am getting GPS locks usually within a minute.
