Alltel ROM vs JD's 6.1 GPS ROM - GPS Performance Poll

[gedster314]

I have mixed results with JD's and have spent no time with Alltell's. I ususlly get a fix within a minute or 2. It did seem to do ok with Google but when I play with Live Search I seem to get a more accurate location plot. But then if it's within a half block who cares.

I will play with it some more but I see it as everyone is still learning and I think after a few Rom versions we will have some pretty respectible gps roms. So far this version of JD's rom hasn't frozen, locked up or taken a deep sleep. To me that's good, GPS is Icing on the cake. I don't seem to have Revison A in my area because I am getting the same speeds as before but my audio streaming does seem more consistent.

Can't wait to see what the official Sprint GPS/A rom will bring to the table.

Oh yeah, I did try these last night and I got my gps working within a minute or two without resetting. Worked after tethering for a couple hours, and when I woke up this morning. Without resetting. I'm using OMJ's rom, didn't do the 1-2-3 files thing. The only thing I did was I cabbed up something. And when I tested the cab I left it on my device. Anyone else wanna try this and see if it helps? It kickstarts your GPS and loads it on every boot. Here is the link:

i tried that and it doesn't cause any harm but it doesn't help me get a lock with the gps.

with JD rom I get GPS but no Rev A

since Rev A is more important for me right now so I switched back to Alltel Rom... I use my other device for gps anyway so I am too lazy to mess with it right now... GPS probably work on Alltel too but I am thinking of cooking my own ROM...

I'm connecting very quick after a soft reset. Using JD's rom. I had all sorts of problems inside at work but now in my apt. it's fine. I think if I just watch that it doesnt suspend while running it should be fine. (famous last words)

No I didn't install any extra apps or make any tweaks to get the 30 second fix. I tried installing quickGPS but the lock time seemed to get longer so I actually uninstalled it. I haven't really played around with it much yet. I'll try some experiments and see what happens.

EDIT: I'm using JD's original ROM.

That's the same behavior I am getting...

I voted Alltel and flawless, but feel I must change my answer. Now I would have to say mixed as the GPS sometimes simply wont get a fix in short order. Sometimes a soft reset fixes it, sometimes it doesnt. Today at lunch it took two soft resets. Ive been using visualGPSce tp kickstart it most of the time, but I dont really think the program that initiates it comes into play. All that program does is interpret the NMEA signals that the gps unit sends it. And I get plenty of satellites quickly, so the actual chip isnt the problem.

I dont understand why the almanac doesnt seem to save somewhere in the machine. I also dont know if the quickgps does anything valuable.


Good thing I have a garmin vista hcx to tide me over until I get this fixed, although I was hoping to sell it on ebay, but might hang on to it due to its incredible battery life.

Mine refused to connect this morning in bad weather in the car, waited 10 minutes for Google Maps. Then I soft reset and Bingo Google Maps locked in about 2 minutes.

AllTell 6.0 ROM.

So it does seem that things can get wedged.

So My new rule is, if I really need it and don't want to chance a long wait, soft reset, run Google Maps (outside) then run iGuidance (with GPSGate) and I'm ok every time. I can live with that if it stays consistent.

I need to play with GPSView and see if that helps any, I don't think it will.
