Help, not sure what I need...

[jhinze]

Although I'm not a noob to flashing I am to my new phone.

I just got the TP2 worldphone version from sprint (model T3780) which replaced my old Diamond.

After reading what I need for unlocking and flashing am still a bit confused...

Can I use the HardSPL in the RhodiumW CDMA Worldphone HardSPL Unlocker Release Sticky or do I need the security/sim unlocker from the XDA group regardless. I have no plans right now to switch carriers so will be staying with sprint.

I've had it for a week and am itching to get a custom 6.5 ROM installed but do not wish to brick the phone by using the wrong unlocker... and then the whole radio thing... not sure if I need to do that as well?

Any advice is welcomed...
