Not asking for much help but a bit of guidance

[juniorseau55]

Going to get an htc touch, xv6900 verizon soon and needs to be unlocked. Would anyone be kind enough to point me to the links that will enable me to do the following:

Unlock the phone
Implement Diamond interface
proper gps usage modification if needed.

I need to unlock the phone with a software I seen around, I seen a few tutorials in regards to that. What rom should I use for the diamond interface? And the gps?

Any recommendations would be helpful!
