iPhone Internet sharing via Bluetooth

iOS 4.3 and later

These instructions will work with iPhone 3GS and iPhone 4 with iOS version 4.3 or later.
You can check iOS version in Settings > General > About > Version
If your version is lower than 4.3 you can upgrade it via iTunes.
  • On iPhone: Settings > Personal Hotspot > ON
    If you get a warning that Bluetooth is Off. Press Turn on Bluetooth
  • On computer: Open Bluetooth Manager and add a new device. Exact procedure depends on Bluetooth software you are using. An example using DELL Latitude Bluetooth software:
    1. Bluetooth Manager > New Connection > Express Mode
    2. Select your iPhone from the list of discovered devices and click Next
    3. Double click on your iPhone name which now appears in Bluetooth Manager device list.
    4. Enter any passkey (e.g. 9561) and click OK
    5. On iPhone you should have a prompt to confirm the passkey. Enter the same passkey (e.g. 9561) and press Pair
You should be connected now. Pairing settings normally gets saved on computer and iPhone so next time you want to connect:
  • On iPhone: Settings > Personal Hotspot > ON
  • On Computer: Bluetooth Manager > iPhone > Connect

iOS older than 4.3

With iOS older than 4.3 procedure is similar, but instead of Personal Hotspot you need to enable Internet Tethering:
iPhone > Settings > General > Network > Internet Tethering > ON
Also make sure Bluetooth is enabled:
iPhone > Settings > General > Bluetooth > ON

If you have iPhone 4 with iOS v4.3 or higher it's normally easier and more convenient to share your data connection over Wi-Fi personal hotspot.

iPhone and Google Apps - Sending emails from Gmail alias (nickname)

Sending emails from Gmail nickname

If you use default iPhone Gmail IMAP (or MS Exchange) setup wizard, all emails will be sent from the primary Gmail alias. If you try to use an alias in the wizard it will not work as Gmail won't allow you to login using an alias. iPhone also doesn't allow to manually enter custom email address in the "From" field.
Luckily you can work around this by setting account usingĀ custom IMAP setup.

Let's say in Google apps you have primary email address This email address is being protected from spambots. You need JavaScript enabled to view it. and an additional alias (nickname) sales@domain.com. If you want iPhone to send emails from This email address is being protected from spambots. You need JavaScript enabled to view it. perform following setup (you must have This email address is being protected from spambots. You need JavaScript enabled to view it. alias already setup and activated in your Google Apps domain settings)
