Yikes, based on this thread and the Google forum, it seems like a lot of people are having trouble.
Google has not made official the list of devices supported, it merely says "Many Windows Mobile devices." It also does not state the networks that are supported. Grrr!
Based on what I am reading, people with same devices depending on their regions are having trouble. Also, some devices do not seem to work period.
"If you have a Java-enabled (J2ME) device, BlackBerry or Windows Mobile device, you can easily check whether or not My Location (beta) is available. Just to go "Help" > "About" from the application. If the box contains "myl: N/A," it means your device isn't reporting a cell."
For me, I do NOT see the "myl: N/A," in the Java application and the My Location stuff works. Hope this helps.
Based on the above link: "Google takes geo-contextual information [from anonymous GPS-readings, etc] and associates this information with the cell at that location to develop a database of cell locations."
So it seems like someone has to roam in your neighbourhood with a GPS enabled device first so that Google can have the cell-tower location in its database. That would explain why some devices work in one region and not in the other.
I tried it on my Dash, T-mobile WM6 rom, Sim unlocked running on T-mobile, that has been reliable untill now. I got the same location unavailable message untill it crashed my dash. It took multiple tries (over about 10 min) to get it to perform a hard reset. This is the first time I have had trouble with the Dash and it has been reliable since the hard reset (i did not reinstall google maps).
Be careful and try it at your own risk.
Ill stick with Live Search at least until this version of google maps comes out of beta.
While I have v2.0 on my Wing, I still have v1.2 on my Dash. How do I update to 2.0 on my Dash? I see no provision for it on the menu page.
Also, do they use any proximate cell towers, or only those with my carrier? Probably a silly question. But in an area with few towers from any carrier, then gps would be much better.
If you have built in GPS, I believe Wings does, then you can make use of that to get accurate reading. Google Maps 2.0 beta supports the GPS.
No, actually neither the Wing nor Dash have built in gps. They do support bluetooth gps receivers, I've used one on my Dash but can't get it to quite work on the Wing.
I've since found the link to install the cab file on my Dash. I tried it but got the position not available. However I suspect this is due to the fact that my primary sim is in the Wing and deactivated sim is in the Dash. I upgraded via wi-fi and tried G-Maps the same way. If my sim were in it it probably would've worked.
I downloaded the Surreal Network appunlock cab, ran it on the phone, rebooted, and the next time I tried the "My Location" feature, it worked! I was a good deal off, and my actual location was well outside the "circle of error" surrounding the blue dot. However, I was in a remote location, and it was the first time I had tried it. At least it got me in the right part of town. Hopefully, accuracy will improve as I use it more, and where there are more towers.
