Navizon iPhone GPS: the Amazing Hacker Development Continues
I feel like it is Christmas every time I open my iPhone installer.app lately. Along with VNSea, NES and MobileChat, here comes another AMAZING developer-hacker application. I don't see Apple having 1/2 of this stuff by the time the next release is out. AS a matter of fact, I don't see a lot of hacked iPhones going legit any time soon.
Back to Navizon: Using both cellular triangulation and a DB of Wifi hotspots and ISP IP addresses, Navizon is able to provide a semi-accurate view of where you are at a much faster rate than most GPS systems. Granted the accuracy of the device depends on a lot of factors, and your results may, of course vary.
The Navizon.app also just throws your coordinates into the Maps application and puts a little pin where it thinks you are. So, so clever. In my informal tests, it was about 500 Meters off at my home and about 200 meters off at work. Each of these results used cellular data and got the information in just seconds.
The number of applications to deliver content using geograhic location on the iPhone are virtually limitless. I am sure developers are hard at work on more applications that take advantage of this knowledge. If Google Adsense isn't all over this then someone needs to get fired, yesterday.
I can't wait to see where this application goes, how exciting! Get hacking!
OH, btw, it DOES work in Europe - at least France.

Even the included maps application has items that are useful. Nearby shops, restaurants, etc.
This is truly amazing
I live minutes from downtown Portland, OR. Needless to say, my cell reception is always impeccable and I can see dozens of WiFi networks, including open ones.
Navizon searched for about two minutes and said it couldn't locate me. Oh well.
When are they going to start developing iPod Touch hacks. I mean, I know there are some hacks that require Cell service but most do not.
They haven't been able to unlock the iPod Touch yet, but they're working on it. No apps until they're able to unlock it.
Yeah I've been trying this since I saw it in installer.app yesterday and hasn't been able to locate me once...
I'm in Seattle...
It works in Atlanta... at least in the two locations I've tried so far. As for the ones that don't work; tell the developers! Posting here isn't going to get you results.
Really? i live in atlanta..havent found a place this works yet. Or Orlando, i was just there for the weekend.
I'm near Dallas Texas and it can't find me...
ip location providers like hostip.info need info from isp's in order to get this right...
not all isp's provde accurate data sets to those sites... if they don't supply that data no or an inaccurate result will be displayed...

so does Navizon specify which isps provide it with the necessary info, so users of said isps could confidently use the app? (Or, is that even a logical conclusion to draw?)
Looks like Navizon is dependent on volunteers with gps devices to collect local data about wifi and cell tower locations. Pretty automatic apparently and a small payment available for the help.
Should work much better as time goes on. Maybe about the time an actual iPhone gps interface is available...
how do u gather the gps info around ur town to get points i bought it aready
Nowadays, mainstream usage mostly refers to computer criminals, due to the mass media usage of the word since the 1980s. Unlike the definition in the RFC given above, this includes script kiddies, people breaking into computers using programs written by others, with very little knowledge about the way they work.
