It depends on the quality of the GPS reception of your iPhone where you are. From 15 to 30ft. in ideal conditions, it can be lessened to hundreds of feet in certain locations, such as underground parking lots.

In case of insufficient GPS reception, your iPhone then uses GSM triangulation and WiFi hotspots to determine your position. The precision is thus quite imprecise, especially without any WiFi hotspots around.

From the menu, hit the “Record position” label. A map of your surroundings is displayed, centered on your current location. The precision level is indicated at the bottom right of the screen.

Hit the “Record position” at the top left: the address (street, city) of your position is displayed (except in rare occasions, such as you being in the middle of a desert or ocean). Your latitude and longitude coordinates are also displayed.

If you wish to, you can enter a short description for this location and associate a picture.

From the menu, hit the “Record address” then enter the address you’re looking for, like “Times Square New York City”. A map of the location is displayed, centered on the address you entered.

Hit the “Record position” at the top left: the address (street, city) of the place is displayed, as well as its latitude and longitude coordinates.

If you want to return to a previously entered location, select it from the location list.

Should you need to use the last recorded position, hit the “Go back to position” label on the main screen, which will display a map of that location. Hit the “Current position” label to switch to a map of your surroundings: a blue arrow will be displayed showing you which way to go and how far your destination is.

You can switch from your current position to the destination or a global view of the itinerary by using the button at the top right of the screen.

Hitting the “N” (North) button at the bottom right will make you enter the compass mode: the map is then always orientated according to the direction your iPhone is pointing to. Hitting the same bottom right button will exit the compass mode: the map is classically orientated to the North.

You can have access to a more detailed itinerary by hitting the “Go there” button of the recorded position, which will display the Google Map itinerary.

If you want to send a previously entered position, select it from the location list.

From the main screen, hit the “Send position” label then choose between e-mail and text message.

From the menu, hit the “Location list” then choose the one you wish to use: directly hit the line to display the related location on the main screen (it will then become the main position), or hit the blue button on the right to display it on a map and then enter the itinerary mode (thanks to the directional arrow) or the Google Map screen (thanks to the “Go there” button).

On the Favorites list, simply hit the “Action” button at the upper right: a CSV file is then generated. It contains a detailed list of all the positions you entered and can be sent by e-mail.

Application data backup is a built-in feature of your iPhone-iPad and iTunes, as long as you regularly synchronize your device with iTunes on your PC or Mac.

At the beginning of the syncing process, iTunes saves the following data from your device:

• Contacts and Contact favorites
• App Store Application data
• Application settings, preferences and data
• Music, videos, photos, etc.

When you change your device, or even with your current device, you are able to restore that backup with iTunes. You will thus be able to retrieve all the data and content saved during the last syncing.

For more information about backup saving and restoring, please visit: http://support.apple.com/kb/HT1766?viewlocale=us_US

You can also use the “iTunes Database export” feature (see below) to run an individual backup of your application data. Be careful to properly save the “Database_Export.db” file on your PC or Mac.

Running iOS 5 or higher with a valid iCloud account, you can export your application database from your device to another device (iPhone, iPad or iPod touch) using the same iCloud account.

A) From your source device (device A):

• select About, Settings, Database Management, Import Export
• select “iCloud – Export Database”

B) From your target device (device B):

• select About, Settings, Database Management, Import Export
• select “iCloud – Import Database”. Check that the date and time correspond to the file you exported from device A.
• just confirm the import by clicking on “Yes” in order to replace the former database of device B by the one just transferred from device A.

Once finished, device B contains exactly the same app data as device A.

Note 1: iCloud sync may take several minutes to complete, especially when data size is large and Internet connection, slow.

Note 2: if you have just installed and launched the app on device B, you are advised to wait a few minutes for the app to sync with iCloud, before exporting your data from device A.

This process will allow you to export your application database to another device.

A) From your source device (device A):

1. select About, Settings, Database Management
2. select “iTunes File Sharing / Export Database”
3. connect your source device to your computer
4. in iTunes, select the device (below Devices), and click on the “Apps” button.

8. select “iTunes File Sharing / Import Database”
9. Just confirm the import by clicking on “Yes” in order to replace the former database by the one just transferred.

Note 1: the Export feature can be used to back up your app database: in this case, select the ‘Database_Export.db’ file in iTunes, and click on ‘Save to’ to back it up on the chosen support (hard disk, USB storage, etc.).

Note 2: another way to back up your device is to Sync it with iTunes.

Note 3: you can use this feature to transfer your data from the Lite version (export) to the Full version (import)
