When BlackBerry Device Software 4.1 is used with certain wireless service providers, Short Message Service (SMS) text message corruption occurs when sending an SMS text message using a DatagramConnection. The text that is received by the SMS recipient appears garbled.
Complete one of the following:
Use a MessageConnection instead of a DatagramConnection.
Upgrade the BlackBerry Device Software.
Note: This does not affect SMS text messages that are sent from the Messages application on the BlackBerry smartphone. This issue only applies to third-party applications that use a DatagramConnection to send SMS text messages.
