To use i-Hoot after you have downloaded it, you need to create an account from your iPhone only. If you are an existing user of STI prepaid, you can use your existing account. Otherwise, you need to create a new account. Once you are done with your account, you will be able to see your address book through i-hoot. Just click on any contact and it will call a toll-free number from where it will connect you to your contact. Please note that this Toll-Free number will cost you airtime minutes as toll-free numbers are not free from most cell phone providers. You can also call a person by dialing his number. For US, dial 1 + Area Code + destination number. To make international calls, dial 011 + Country Code + Area Code + destination number. You can see your balance on screen which will tell you how much of balance you have in your account.
