Slow GPRS connection with FC2


I'm trying to connect my PC with my T39m cell phone, using a Bluetooth USB adaptor. I use Fedora Core 2.

GPRS connection goes well, but using pppd sometimes I get a "Serial line is looped back" error and everything stops.

Even when I'm successfully connected, connection speed is terribly slow (0.3k/s or less). I've tried the same connection under WinXP, et it works fine (and FASTER).

What's wrong? Please, help me
