i have the blackberry pearl 8130 with verizon. i just bought a blackberry belt clip holster for it. with the holster provided with the phone i could make a call and slip it back in and talk with my earpiece and it wouldnt hang up on the person. with this new belt clip holster after i answer the phone, if i slip it back into the holster it hangs up on the person. anyone what settings i need to change to fix this?
