Trying to kill SPRINT in ppc and give myself FREEDOM !HELP!

[sekretspy]

HI really I need help, i recently bought from a friend a ppc6700 who had it with sprint its perfectly legal, I’ve already unlocked the ExtRom, erased the sprint extras and upgraded the wm6 Helmis now I have a couple of questions
1) Why if I already erased the sprint files from my ExtRom does my phone still say Sprint PCS?
2) When I configured the carrier customization on HELMIS,what exactly does this do?
3) Why when I tried to configure the helmis on the title bar, if I selected another carrier other than sprint the device rejected the ROM upgrade?
4) Is it still locked?
5) If so how do I unlock this?
6) What else would and do i need to do, so that when i take it to my other CDMA carrier they'll be able to connect the PPC6700 completely calls txt messages and internet access?
If possible please email me at
