i did Optimus V swap for my Sprint S3 for Virgin Molbile usa (im using prl 61007 on stock sprint rom)
when i need to use QPST/DFS i just flash LJ7 Modem and use the 16 digit samsung password
anyhow im pretty sure i got everything working (mms, sms, streaming, data and voice) BUT i still have a couple questions

01 if i ZERO out the MDN and MSID and reboot phone the phone wants to do hands free activation but always fails
02 if i go into phone settings and try to update PRL it also always fails

i know the OTA probably needs a virgin mobile activation apk but to update the prl i wouldnt think it would need that.

any help would be great.
