Hello,
I have a Nokia Astound C7-00.1 I got from T-Mobile on 07-13-2011 and installed Boldbeast version 2.7 and could not be happier - IT WORKS WITHOUT BEEPS ON BOTH SIDES!
Good job Boldbeast programmers.
Only tested one day and did find once glitch but do not think most users will every use the feature:
If you use hot key by hitting Application Button three times to get the summary, during a call, it will beep once on both sides of the conversation - I sent a seperate message to Boldbeast about this but is a very minor problem for I do not need the feature.
