phone in won't work

on my PSP1001 running m33 3.90 Furikup v0.1.12 makes calls to regular/mobile phones fine with helicopter noise (heard by the person you are calling) in the background, when someone calls the psp, it rings and I answer it's just helicoptery static on the psp side (can't hear the person at all) and what sounds like interference on the other side(its sounds like other peoples phone conversations with static - nothing from the psp)

this is not a complaint (this program is sweet, good job)
I was just wondering if there is anything I can do to be able to recieve calls on my psp with atleast the quality of the calls i make from it.

UPDATE
******
I installed the m33 3.71 phatms thing in order to get the new mp3 plugin CFE to work which worked, but now i can't get past the network selector at all, i've read that it happens to people infrequently but i have tried over and over it just hangs everytime, now i wish i wouldn't have installed that phatms thing, what are u gonna do but wait and hope the noobz crew will have another release of this sweet program, I tried looking at the source (i am currently learning c++) but i am not at the level of programming yet where i feel comfortable messin with this code, does any body know if this code is in C or C++?
