Let me get this straight for you guys once and for all.
aGPS is short for assisted GPS, it uses a Server from a carrier. It will use KB, which uses data. You don't need a plan, just a cellular #777 connection.
Standalone GPS is a chip inside the phone wich doesn't need any type of connection. No WiFi or Cellular Data.
Some Maps such as Google Mpas, use the Internet to pull Map info.
So you can use Standalone GPS with no Data Connection if you're on a Custom ROM that NEVER has had offical MR1 Verizon WM6.1 ROM, if t does you need to revert the PRI. If you're on MR1 you can only use aGPS with the Vahilla cab, although I never got that to work for me...
Offical MR1 can not use Standalone GPS as Gay Verizon locked it.
Hope this helps with people confused and those giving out bad imformation. I know this because I have tested every method
