I'm sending my phone to LG as well (different issue), but all I know is they said it takes 5-7 business days to get your phone back. Out of curiosity, what city are you sending your phone to?
Phone has been shipped to LG, lets see where this goes. Will post back once I get it back.
LG has shipped the phone back to me and said they repaired the following. Will post another update after I get the unit back and am able to test it.
The unit was repaired, main issue GPS issue, GPS assembly fixed. Repair on Antenna contact.
