New ROM/Radio, same GPS issue

As you guys can see from my post count, I rarely post here for questions, because answers are usually very easy to find if you know how to search for them. However, I've been flashing ROMs since the day my Rhodium came in the mail. That being said, I'm not really looking for an answer, per say. I'm asking for opinions tonight more than anything.

(All GPS tests were done outdoors on cloudless or mostly cloudless conditions)

I posted a while ago that I was having issues getting a GPS lock after updating to the 04 Aug version of 23673 Cookie Energy ROM. I've been using the 4.49.25.91 radio for quite some time now. I'm on T-Mobile and get very fast data speeds as well as zippy bluetooth transfer rates and awesome wifi connections. The problem seems to have happened with only the GPS. :(

While using the July releases on back with the radio version, I had no lag on the GPS and got locks within 20 seconds or so. With the advent of the 04 Aug release, I was unable to get a GPS lock at all. I tried all my usual setups. Running QuickGPS, HTC GPSTool, ChartCross GPSTest, and Google Maps turned up no positive results. I was unable to get a lock at all. :confused:

I tried a complete reset to make sure that nothing was messed up. (T29, ROM, Radio) This didn't change the problem. It still happened with a fresh ROM.

My next test came in with flashing a different ROM to see if I could narrow down the culprit. After trying Core Cell Evo V3 (23126) and DeepShining X9 (23128) I confirmed that both of these ROMs do not experience the same problem with the GPS connection as the Cookie Energy ROM. I even reflashed the 24 July Cookie Energy version that I was running before and got a perfect lock.:o

I flashed an older radio 4.49.25.57 to the phone to see if that fixed it. It did.... sort of. I got amazingly fast GPS locks. (5-7 seconds - I'm not kidding at all.) Bluetooth seemed alright, but speeds weren't quite as fast. Wifi was about the same. Data speeds were kind of weird. I would get a 3G signal, and it would drop the connection when it switched back and forth from 'H' to '3G'. (I vaguely recall this happening to someone on XDA before a while back.) When it remained stable enough to use, the speed was about half of what it normally was, so I ended up switching off 3G and stuck with EDGE, which yielded positive results.:cool:

I then noticed that a newer ROM version had been released. I quickly did task29, flashed the 06 Aug Cookie Energy ROM 23673, and flashed the 4.49.25.91 radio again. Before installing anything, I tested the GPS again by running QuickGPS then ChartCross GPSTest, HTC GPSTool, Google Maps and allowed each program to run for 15 minutes or so. No luck at all. I had just about given up, when sitting in traffic today, I flipped on Google Maps and got a lock in under a minute. I'm not sure why. I played around with it for a while throughout the day until the rain moved in and found that if it sits with no lock for more than a couple of minutes, it won't pick up anything at all. So it seems pretty random, but it SOMETIMES picks up a signal. When it actually does pick up a signal, it gets 11 or 12 satellites each time and holds them. :confused:

My question is what have you guys done to improve lock times on your devices, if anything. This radio used to be awesome, but it seems to be annoyed with the current ROM version for me.:)

I notice that several people have posted about other wireless related problems with the weather updates. I doubt these are related, as no one else has posted anything like this silliness I've got here.:D

I really wrote a lot here, huh? I hope some of you were able to bear with me through that. Maybe if I speak up more I won't be so long-winded next time...;)

***Edit: I forgot to mention that I tried each of the tests listed with aGPS both enabled and disabled.***
