GPS Locking quick using the Telus IP on WM 6.5 over here. I was having problems with the old IP, but switching to the Telus seems to have fixed the problem...

This was also helpful on getting me going because after much tweaking I must have screwed somthing up and it would take about 15 min to connect to the network after soft reset:

The phone is taking (forever) to acquire service after the flash.
Solution: Toggle M.IP PST Settings
If the phone doesn't have a signal, dial *22803 or *22802 and hang up when you get a signal.
Now that your phone has a signal, you dial ##778, it should bring up a program, press 'Edit'.
The unlock code is 000000 for Verizon users.
Select "View Info" > "M.IP Settings"
Change MIP_MODE, Reg. Retries, Reg. Timeout, and Pre-Reg. Timeout to other values.
Soft-reboot your phone.
When you acquire a signal again, dial ##778 once again.
Go back into Edit > View Info > M.IP Settings.
Change the values back to what they were:
MIP_MODE = M.IP Preferred, Retries = 2, Retry Timeout = 1750ms, Pre-Reg Timeout: 0.
