Woah. I think I may have AGPS working again, at least it *looks* like it.
Note: This is for T-Mobile USA customers only. I suspect a lot of US users use their N900s on T-Mobile USA anyway because their 3G bands works with the N900. If you're not a T-Mobile USA customer, sorry this will not work as T-Mobile has this SUPL behind their firewall, so you have to use your data plan to use this server (and not wifi).
1. Goto
http://dp.t-mobile.com/pki/
- download and install these certificates:
T-Mobile USA Root CA.crt
T-Mobile USA Issuer CA 05 v1.crt
T-Mobile USA Intermediate CA 01.crt
Details later
2. Set your SUPL server to lbs.geo.t-mobile.com
3. Reboot (not sure why this is needed, but somehow it started working after reboot)
Now I can't totally vouch all these steps are needed but somehow, after doing these things, I turned my "10 minute blinking satellite icon" to "blink twice and stable" and get a lock that's within 2 miles even without satellite information. This is very indicative of some sort of AGPS lock I think.
Edit: I do have to admit, the "locks" I got were worse than what I got when supl.google.com was working - they're like 3 km instead of ~1.5km with google.
If someone could verify this as good that would be nice too.
