I recently bought a Nokia 6021 mobile phone,
with v. 04.10 firmware released on 07-09-05

When I try to enstabilish multiple connections over IP with my PC using mobile phone as a gprs\edge modem (via Bluetooth), it often resets the connection or even reboots (it switches itself off and on again (without requesting pin)).

This problem seems to increase notably when using bittorrent to download latest OpenOffice. I haven't figured out if the cause is too many halfopen (set to max 10) or total connections (although when I create more than 110 multiple connections 6021 always crash, less than that crashes in about 15min)

Can anyone help?
Is out there a new firmware release?
Can I work around the problem someway?

Thanks in advance
