  • Anonymous Dec 27, 2008

    It says a welcome screen should appear 24 hours after purchase.
    It's been 24 hours and still nothing.
    But I talked to a t-mobile worker on the phone and she said to wait at least 48 hours from when you first turned it on.

Downloading songs(mp3) to your sidekick is very simple. Connect the phone to your PC or insert your memory card. Open My Computer, open SDCard or Removable Disk, Open My Music and simply drag and drop the music files ih that folder.

To register....

  1. Have your phone (Sidekick or otherwise) with you
  2. Visit
  3. Click "Register for My T-Mobile"
  4. Enter your 10-digit mobile number without spaces (e.g. 5557771234) and click "Submit"
  5. Your phone will get a text message with your password. It will be something like ar1wo6 and it is CaSe sEnSiTiVe!
  6. Log in using your mobile number and temporary password
  7. Fill in the information the page asks (note: you will be asked to provide a new password, and if you are using a Sidekick, this will also change your Sidekick login password)
  8. Select your phone from the list if prompted

Register sidekick 3

You need to call T Mobile and ask to be transferred to the Sidekick department where they need to speak directly to YOU to register it. Have your parents nearby so that they can allow you access to the account seeing as they probably are the account holders. Good Luck, my brother had the same issue! Merry late christmas!
