SMS/MMS/E-Mail Message Block Utility.
BlockUs automatically blocks every attempt to send messages from your device. Blocked messages are placed in a special folder. You decide which messages are un-blocked by creating customized un-block rules based on supplied recipient addresses. For added power, BlockUs supports partial rules.
This little utility also allows you to peruse all sent messages on your device, by taking into account their blocking status. Easily find out what messages were sent (or for which an attempt was made to send them) for any given day.
A Multi-Lingual User Interface to over 140 languages is available.
For added power, combine this handy little utility with MobileTimes' advanced search tool FindUs!
Support exists for Windows Mobile 5.0 & 6.x (6.0, 6.1, & 6.5) for the PocketPC/Professional and SmartPhone/Standrad platforms. Released as shareware.
