Choosing which Skype account to use with telyHD is a personal decision. See below for some considerations.
Note that any changes you make to your Skype account on telyHD, including contact changes, will be seen on your other Skype clients (for example, Skype on your computer), and vice versa. As with any Skype client, your Contacts list and account settings are stored with Skype, not on telyHD.
Note also that you can store multiple accounts (used one at a time) on telyHD. So, if you’re unsure which option to choose, try both.
If your situation falls between these two scenarios, you can begin with your own account and switch to a new account later if desired.
You can create the Skype account from a PC or Mac if easier.
To use multiple accounts on telyHD, simply sign out of your current account and sign in to the next account (or create a new one). Each account will be stored as its own card on the Contacts screen.
