Alright, so what I'm gathering from the files here
http://forum.ppcgeeks.com/showpost.p...8&postcount=29
is that the
00068.zip is a PRL that you would have to load into your phone in order to use Metro's towers.
As I recall, GetSPC is a program designed to pull your PSC (A unique number for each phone) so you can in turn unlock your phone.
mms.zip seems to be the specific mms app that you would need to load into your ROM in order to get the mms to work properly.
Hard-SPL-MFG.zip is a program used to unlock your bootloader, so not to bork your phone while flashing.
SuperCID is a utility used to actually change your phone into a "Metro" phone. Sort of like a virtual SIM card for CDMA phones.
And finally, the three bottom files here
http://forum.ppcgeeks.com/showpost.p...9&postcount=30
are the programs used to actually put the information and configurations onto the device.
I am not 100% sure of the information I've just posted above and if you choose to try and unlock your phone based on my above instructions and brick/mess up your phone, I am not responsible.
