WORKS EXTREMELY well for me. Picks up MORE satellites, much quicker than before even inside my house. Try it and see if it makes a difference for you! Don't forget to reset/cycle power once you change the reg setting.

You my friend are the man! This is the always on GPS connection I have been waiting for. I have been playing with this app right HERE and now with this reg edit it works all the time. Even with not Data connection, no google maps, no live search... All I can say is Nice. Can some one try it with a gps like tomtom or something?

With Tom Tom 6.032 no difference. Only if I use the quick gps do I connect with ten seconds outside. Not inside.

Hrm...this might indeed be a "placebo" effect if what lsme420 has to say is true and this is in fact, the persistent setting for GPS and NOT an AGPS setting. This MIGHT be the reason why it is able to "obtain a lock" quicker, (i.e. it is always seeking since its always on), but this doesn't really explain why it can obtain satellite locks in areas I could not before. Also interesting that lsme420 mentioned that this worked WITHOUT data connection.

Here's an experiment if you guys don't mind. Turn on WiFi, and turn off data, then start up google maps...go to your basement or something where its hard to get satellite locks and then start up the GPS in google maps. See if you can get a lock and time it. Do the same thing this time with an active data connection...time it. See if there's any difference. I'll post my results after other's post theirs.

i dont think the Touch also known as the Vogue has that unlocked yet, but there's an entire section for just that device... i did search for GPS on the Vogue but returned nothing useful, making me think again that it's not avail ... yet

#1.What I mean by always on is. Example.. This program "Vitofindme" would not work unless I had a active sat connection through live search or Google maps prior to running Vito. But since the reg edit I don't need to launch them. This I'm thinking is a-GPS through my radio so if my phones on so is a-GPS.

**"An a-GPS reciver receiver can address these problems in several ways, using an Assistance Server:
, The Assistance Server can locate the phone roughly by what cell site it is connected to on the cellular network.
, The Assistance Server has a good satellite signal, and lots of computation power, so it can compare fragmentary signals relayed to it by cell phones, with the satellite signal it receives directly, and then inform the cell phone or emergency services of the cell phone's position.
, It can supply orbital data for the GPS satellites to the cell phone, enabling the cell phone to lock to the satellites when it otherwise could not, and autonomously calculate its position.
, It can have better knowledge of ionospheric conditions and other errors affecting the GPS signal than the cell phone alone, enabling more precise calculation of position.

#2 The GPS always worked without a data connection. The only reason you have a active data connection with livesearch or Google maps is to load your visual map off the web such as satellite view or road view, not your gps position. Or you would just be a blue ball moving in a big brown field.

#3 It works for what I need it to do.
