Is Titan 3.35 or 3.37 radio better? GPS help!

[gilee]

I know everyone been talking about 3.35 radio, but the Alltel rom comes with 3.37 radio
And since 3.37 radio seems to be newer, is the 3.37 radio better?
I am on 3.35 right now, using the GPS rom cooked by the kitchen. My phone is Sprint.
And my GPS just cannot work. I used every possible method stated in this forum and nothing works.
It works sometimes, and sometime doesn't (no matter what I do) I don't see any possible patterns to when it works and when it doesn't. patterns I look for interms of reset, standby, use for long period of time, inside, outside, just applied the GPS hacks (things I listed below)...etc... it seems like the GPS just works sometimes, and sometimes it will NOT WORK even I reflash and redo everything! (I cooked about 15 times already)

Some of the GPS hacks I did and found from this forum includes: 1,2,3 method, DLLs, register AGPS from 2 to 4, GPSEnable, GPS viewer, GPSQuick, and others that I don't remember. basically Everything!

Please help.
