PPCGeeks - Please Help

Hi I installed SSK 1.5 Rev B with 20744 rom
I have slide to answer with White curtain, and also s2u2 installed there.

Everything works like a charm, but I have one BIG problem.

When I talk my speakerphone turns on automatically after around 1-2 minutes of conversation... It drives me nuts.. the screen is either completely off, of has white curtain on.. there's no way i accidentally move curtain down and press speakerphone button, or turn on the screen (if it's blank) and press it...
speakerphone just simply turns on ....

if anyone please can help me.. i don't want to flash one more time (it's been to many :)
thank you
