Potala Telly 1.21
the author of this app says:
With this phone utility, you simply drag your thumb left or right to instantly change between screens. Unlike other dialers, this program is a replacement dialer for the Pocket PC. When a call comes in, Potala Telly jumps to the foreground and displays in big bold graphics who is calling. You can also set a different ringtone for each of your contacts. The program also has a voicemail navigator screen--use VCR-like controls on the screen to read your voicemail. For road warriors, Potala Telly will give audio cues, including spelling out the names of your contacts so that you can place calls without looking at your screen. You can also send SMS messages.
