Here is what I did:
hard(!) reset -> installed only magicall -> test (only one rule, as described above) -> failed again
The filtered SMS completely disappears as it has never been received at all (only trace is in Magicall Log/Magicall notification) - something I would expect from "Delete" action.
HW/SW info:
- HTC Touch Pro2
- Official WM6.5 (ROM version: 2.07.401.1 WWE; OS version 5.2.21887)
- Sense 2.5 (Manila version 2.5.2012)
Is there anything I can do to identify this? So far Magicall seems to fit all my call/sms filter needs - at least in theory

Can someone else give it a try, pls? (touch pro2 or diamond2 with WM6.5)
