messagingtoolkit

The current version is capable of sending and receiving messages (SMS, WAP Push, vCard, vCalendar, EMS picture, ringtone) using any GSM modems or mobile phones that support AT commands.

It does not support MMS yet. Support for MMS will be added in later version.

There is a plan to add support for Windows Mobile and Android powered phones in latter version without using AT commands since these phones do not support AT commands.
