Mobile is an application optimized for the iPhone, setting up a connection via GPRS, UMTS or WLAN to the SwyxServer. This is a requirement for the use of SwyxIt! Mobile. After logging on to the server, you have access to the global and your personal SwyxWare Phonebook, as well as your Caller and Redial lists.For each entry in these lists, you obtain full contact details such as phone numbers, e-mail address, even an image for the contact. You can initiate further actions from these details, such as calling the contact or sending an e-mail.Within the global contacts in SwyxIt!
