Enjoy, i got this off ebay about a month ago.
**Dont download the files, google the following.
CDMA Workshop 2.7
Should be self explanatory. And to skip the first 2 steps, just call Boost Mobile and tell them "My phone does not have service, I think I need to reprogram it"
And they will provide you the MSL when they tell you to dial ##123456# (123456= your msl)
OP Edit:I have uploaded a new Guide, which does not include the "illegal" method of swapping/changing your esn. It does however include ESN/MEID Locations, and how to obtain the ESN/MEID Locations.
Update 09/06/12 Here are a list of donor phones that will give you 3G
-LG Rumor Reflex
-HTC Evo 4G Design (4G as well)
NO OTHER DONOR PHONE TO THIS DATE 09/06/12 IS A SUITABLE DONOR FOR 3G
I will be updating this list
**For the commands in QXDM or how to change the ESN, google it.
