I found this old prl came from some dealer is special. It's noticeably smaller then current one, but my sprint phone can connect to 1x network very quickly with this prl. The network speed is same, but the connection buildup is quick, it only took about 15 seconds. With the newest prl, my phone will try to connect 3G but finally drop to 1x, the network speed is same, but the connection buildup can took 1-2 minutes.
So I've been using this old prl for a long time. I guess they removed some 3G related stuff in this prl, which actually make connection buildup much quicker, since my phone don't have 3G anyway.
Can you have a look at this prl and do similar stuff to newest PRL? Of course if you can get true 3G then this is meaningless to you.
I tried 3 different versions of your prl. With your newer prl, the download speed is same, but the problem is the time it take to get a stable connection. My phone will try to get 3G connection and have the "3G" indicator, but went back to 1x later.
Another thing is the 51765 is significantly smaller than the newer prl, that's why I was thinking something more were removed.
The older PRL is probably smaller because it has less roaming entries.
That's a good suggestion! I'm using DFS demo, can you tell me where should I modify this setting? There are tons of settings in DFS looks related...
I changed the NAM tab, Preffered settings, Pref mode from "CDMA_HDR" to "CDMA_IS2000". It still spent some time to connect 3G on the first time enabling data, though the second time the connection was built up faster. I didn't see obvious signal strength change, it was actually lower...
I checked the settings with DFS again, it seemed the change I wrote didn't stay, the setting is still cdma_HDR.

Also go into Settings > About phone > Status to see what mode it's running in. It should say CDMA 1xrTT 6 or 7
The upper 3G logo is actually wrong. I have a NS4G running in CDMA only mode and it still displays 3G even tho it's running at 1xrtt
Yes, I unlocked first. From the status, if last time the phone connected with the old smaller prl, the network will show 1x, otherwise it show EVDO. I knew that 3G logo is wrong, but that often means more time spent on connection built up.
