The first question is: Did you re-lock the phone after you installed the DCD ROM on it? In order to install that ROM you would have to have unlocked the phone. Unless you re-locked it, you're still unlocked. If you just want to add Google Maps, go directly to Google on your phone and download the CAB file from there
. The second question is: How did you load your previous ROM? I would recommend BuildOS from PPCKitchen.org. This will allow you to add what you want and keep the superflous stuff off of your phone
. The third question is: Have you ever installed the official Sprint update? If not, then you need to do that first. Get the latest and greatest Radio on the phone and this will ensure that your GPS is ready to use. You should start from scratch by re-locking, then updating with the OFFICIAL SPRINT ROM, then un-locking and then cooking your own ROM.
BE SURE TO BACK UP EVERYTHING YOU HAVE RIGHT NOW, WHILE YOU'RE READING THIS. WHEN YOU FLASH A NEW ROM YOU LOSE EVERYTHING AND IT WILL NEVER MAGICALLY REAPPEAR.

If you don't want to install your own ROM's, you can always find someone else's on here, but you'll need to complete the official update regardless.
