If you're still having GPS issues in an area where you have data coverage, and you've tried changing the gps.conf and possibly updating your libraries as noted in other threads, have you tried changing your GPS settings to MS Based instead of the default of "Standalone"? From wikipedia: Mobile Station Based (MSB) - In MSB mode A-GPS operation, the A-GPS device receives ephemeris, reference location, reference time and other optional assistance data from the A-GPS server. With the help of the above data, the A-GPS device receives signals from the visible satellites and calculates the position. You can do that by doing the following, as noted in my previous post: My GPS was really taking a long time to lock. Usually 10 minutes or so using GPS Status before it would lock. I tried both just using gps only and then also with wireless network and it still took a long time. So I updated the lbstestmode.apk to use MS Based and the gps.conf file that was mentioned earlier and now I get a lock in GPS Status in about 8 seconds from a cold boot using only the GPS with no wireless network. If anyone wants to try, I've attached a flashable zip. I took the zip posted by merkuralex earlier in the other gps thread (thanks merkuralex) and added the lbstestmode.apk posted in this SDX thread: http://forum.sdx-developers.com/index.php?topic=13593.0 The following flashable zips are attached: lbstestmode_mt_gps_conf.zip - contains the gps.conf file from the other thread + the lbstestmode.apk file. lbstestmode.zip - contains only the lbstestmode.apk I'll repost the instructions here (thanks to cornaljoe on sdx for the actual instructions): Pre-1. Flash the one of the attached zips in CWM first to install the lbstestmode.apk (or just copy the lbstestmode.apk into /system/app/ if you'd rather) and then reboot your phone. Follow these directions: 1. After boot create a shortcut to Activities -> LbsTestMode -> .LbsTestMode You may have to install LauncherPro if your launcher doesn't support the activities option under shortcuts. Once installed all launchers will have this option. My note: Just an FYI, LauncherPro can be downloaded from the Market for free if you don't already have it. Or any other app that allows you to create shortcuts (such as AnyCut I think can also do that) 2. Start LbsTestMode and goto the application settings and set it to MS Based and press back until you exit app. 3. Reboot phone and then use GPS Status under a clear sky until you get a lock. The main thing to pay attention to is the numbers labeled Error(m) and Fix/Sat in the lower corners of the compass. Error(m) is the accuracy of your location in meters which shows after you get a lock. Fix/Sat is the number of satellites locked and in view prospectively. In GPS Status, you can do the following to force aGPS data to download: 3A. Click Menu --> Tools --> Manage A-GPS state --> Reset . This will clear all previous A-GPS data. 3B. Click Menu --> Tools --> Manage A-GPS state --> Download. This will download fresh A-GPS data. 3C. Let GPS Status lock. The first time will take longer as your gps/phone syncs the data. After you get a lock, you can try powering down your phone and then restarting and see if your lock is faster from a cold start. This may or may not help you. All I can say is that changing to MS Based helped my gps lock time--I usually have data access where I am.
