Hey guys, I registered just so I could comment on this thread.
I'm a novice when it comes to PPC usage, but I consider myself a savvy computer user so all of these steps were easy to follow. I do have an issue though

.
Whenever I enter my SPC (Read from phone[Step #12]) in QPST it says that it is invalid.
I've done everything step-by-step aside from using your provided .exe file for hex/decimal conversion (It doesn't work when I try to launch it). I found a few websites that have a hexidecimal -/- decimal converter, that don't require a download, and they all gave me an identical number. I can't see that being the issue.
I haven't had any problems until now. Any ideas?
I'm going to retry everything in the morning, I can't think straight atm. Any help would be appreciated seeing as I bought this phone with GPS as one of the main selling points for me.
