Yeah, I agree with alphacow. I don't see how that could possibly work unless it had a GPS built into the phone.

a lot of the newer cell phones have gps location hardware built in so that if the person calls 911, the operator would be able to track the location of the person.
I don't know if it's possible to use it as a gps navigation device though.
I think there are 2 types of GPS, if i'm not mistaken. GPS location and a combo of GPS location and GPS navigation, and cell phones cannot be used as as navigation.

I don't see why they couldn't be used in combination with the PDA and its navigation software. The CF gps units simply provide location AFAIK. It's the PDA navigation software that gives you the navigational ability, right?? Why would it matter if it (gps coordinate information) were coming from a phone or from a gps unit?
The real question is whether or not the gps coordinates from the phone are available for access from the pda. They might only be allowed to be broadcast back over the nextel network (or other wireless network in the case of another provider).
911 calls are traced using the cell signal, not gps location. I don't remember seeing any cell phones with gps built in. I could be wrong about that, but I'm pretty sure thats how it works.
Note the paragraph in that last article that says "As required by the FCC, Sprint PCS plans to sell only GPS-enabled phones as of Dec. 31, 2002".
This pdf file from the fcc's web site documents their testing of built-in gps vs. triangulation for location determination. This one talks about the timelines for the mobile phone companies to meet the 100% gps enabled guidelines. They refer to them as ALI capable (automatic location identification) phones.
ALL mobile phones are going to have gps, and while it is purportedly for your own protection, it does present us with a double-edged sword.

Dudes, I have the i88 phone from Nextel (Motorola) & it definately has a GPS built into it. I've tested the i88 GPS next to several handheld models & it's reported postions are always spot on. I've wondered the same thing myself, but I haven't tried it yet. The GPS in the phone only runs when you hit "update position" or an application (JAVA, 911, etc) pings the GPS. I'm sure someone could write a JAVA ap that'll run the GPS continuously & output it to the phone connector, but I haven't seen one yet.
If someone does figure it out, I could be online AND have updated GPS position on my Axim while anywhere. Ahhhh...
We've written a few location-based Java apps on Motorola/Nextel iDen phones with GPS built-in. The memory and processing power on these GPS phones are quite limited. The phone cannot be used as a "stand-alone" GPS receiver. The apps need to "communicate' with the servers to read GPS and geocoding information.
For the time being, I don't see how the GPS phones can be connected to the Axim as a navigation device....
I believe that a custom ROM should be able to do the trick...

i'm trying to accomplish the same thing right now. my girlfriend has a nextel i88s and i just purchased one myself (eBay @ $69). i have used the standard serial cable available from nextel to connect from the phone to my sony vaio laptop and it worked like a charm! the phones menu gives you the ability to turn NMEA output on or off. NMEA is a standard communication technology for GPS. most software reads NMEA. with the NMEA standard output turned on, the computer receives the necessary signal and tracks it on the software. I successfully used it with microsoft streets/trips, as well as a few others that i tinkered with.
the accuracy for the phone itself when standing still will give a fix of accuracy down to 25 feet. i wasn't sure how well i could trust the details it was giving me until i took a few random readings with the phone and a high dollar garmin unit that my police department uses (good friends of mine). i was pleased to find the similarity between readings from the non-waas enabled phone to the waas enabled garmin - the readings were 95% the same! even when moving the unit was still fairly accurate. cruising at about 75 mph with both units, the i88 connected to the computer and watching the garmin's own display - the readings stayed together though the refresh rate at such speed left a tiny bit to be desired on the i88. still not bad at all when you consider its a CELLPHONE!!
now, getting the phone connected to the axim x5 may be a different story, but i'm gonna try it. thinking about going with the gomadic cables everyone speaks so highly of. if anyone is interested - i'll try to post my findings on here after i get everything in and try it out!
