tell me text works pretty good, hope it helps
This ZIP file contains the TellMeText CAB file and also a CAB file which will install the BlondieSoft Windows Mobile certificate to your device. This is required so that TellMeText has the priveliged access that it needs in order to intercept SMS messages.
Please install BlondieSoft_MobileCertificates.CAB first and then TellMeText_Signed.CAB
