Sprint PPC 6700 MSL need

[trickd122]

I recent purchased a SprintPPC 6700 from a guy who upgraded to the 6800.
I called Sprint who was willing to give the MSL# however stated that the ESN was not on record. I had a friend use the Getspc to retreive an MSL# however that was a filed attempt. I read somewhere, here I believe that if a master reset was done then the MSL would reset to 000000 needless to say that too was a failure. Not sure if this helps but here are the ESNs at the back of the Phone! I need to get this on the mertro PCS network

HEX ESN: 55378008 ()
DEC ESN: OU812

HELP!!!!!!!
