LOL. Wifi and GPS have nothing to do with each other.

Actually, I believe they do, but not how you think. I believe Google's location service has a database that contains info about where certain wi-fi routers are located. At some point, someone had GPS and wi-fi on at the same time and so Google's location service program said, a-ha! this wifi router (uniquely identified using its MAC address) is located at X degrees North and Y degrees West. I'll remember that. So next time you run wi-fi, but not GPS, the program says, a-ha! you're near this wi-fi router, so according to this database, you must be near X degrees North and Y degrees West. And since wi-fi has a range of only a hundred feet or so, you get a very accurate location fix. The cell tower triangulation may factor in there somewhere as well. Basically a combination of GPS, cell towers and wi-fi router locations gives you an accurate reading even if you're in a concrete bunker.

You may also find that if you're outside of wi-fi range, you may get no location. Someone should try it.

I may be totally wrong, but that's how it seems to work for me.

I think your right on target there.

thanks for the info

Actually wifi can be more precise then that there is an app called 'wififofum' it is a wifi scanner that locates wifi points and maps them on a raider...and its pretty accurate..It didn't do too well with height which is expected of wifi but it narrowed down to around 5ft if I was on the same level..it new the direction of the wifi point as well

The scanner is for windows mobile and free..you can play around it with it

IDK if it worked with the stock Google Maps built into the ROM. I downloaded the latest from the market (4.1), and it does work. I've tried it in two places now, and it found my location both times.

Just an update to those lucky enough to be able to charge. I installed the new Sprint ROM, and tried, and it is charging of course as long as you plugged in before booting to Android. Only tried Activesync so far, will try just brick here later. Again I don't know that I would LEAVE it overnight like this, but to give you a trickle charge to get back to 100% at least. But you do need to be plugged in, in windows mobile first. I was not able to do this with all my tests with MightyRom 2.1. And also to note, and I will update later, I haven't modded anything on the Sprint Rom yet, like turning off auto dim etc.

I tried with Auto-dim disabled and it still charged, so it is a confirmation that the Sprint Rom seems to work. Something in Mightyrom 2.1 doesn't.

Again though, I can't stress this enough, I wouldn't leave your device charging this way for an extended period of time, like overnight for instance. Being as the charging code hasn't been completed I don't know for sure it shuts off charging when full, and would hate to see lots of you with blown up phones.

For those that might want it, for testing out the Wifi Tether that stinebd was wonderful enough to figure out for us. http://forum.xda-developers.com/show...postcount=5096 Here is the latest rootfs.img patched with MrPippy's RIL Library modifications. Just extract and copy it over your existing. This will preserve your data for CDMA and give you the latest changes to the rootfs.img. Make sure you are on the current kernel.

Enjoy!

I should note, use at your own risk, stinebd nor I are responsible for any data charges you may incur with your provider. Hopefully you are just seen as phone traffic, but you have been warned!

Ok so?? umm, someone gonna update post # 1 with this new rootfs and is the kernel and module from this gonna be autobuilt and placed on glemsom's site?

I do not think this kinda thing should be released here unless you want to monitor every post to see what conflictions this causes. I too am on IRC and I don't spill over what they post in the chat.

On a personal level, I have not liked your posts about me combining all the files together blah blah and putting them one place for people to download. I don't get what your problem is with that but if it helps people, why shoot it down? Download #'s speak for itself and there are hundreds of people being helped by someone putting all this into an easy extraction. Seems kinda stupid to me.
