Hello, and now for all LINUX freaks, like me 
This little guide for using it with linux.
With linux its not necessary to use a proxyserver, you only need to have bluez-utils installed.
1. first activate bluetooth on your phone, select discoverable.
2. Now on your PC opens a terminal and write : hcitool scan
3. Now you must se your MAC-address something like : 00:11:22:33:44:55 Motorola XX
4. then pair/bond bluetooth device pc-phone with PIN
5. Start Enet2 on your phone : Start, Bluetooth, Internet.
6. Opens a terminal on your PC and write: dund --connect 00:11:22:33:44:55 --channel 5 --msdun 921600
you have 1min. time to make this operation, before i'ts says :Time expired!
7. Now you must see a pop-up window on your phone with the request of a serial-port from the PC.
8. After you have accepted with OK, you must see another screen with the request to insert your DNS
9. insert your DNS after is:208.67.222.222 (i would suggest to insert opendns)
10. Now your connection is active. check it with "ifconfig" on your PC. when you write ifconfig -a on your terminal you must see an active ppp0 connection like this:
Code:
ppp0 Link encap:Point-to-Point Protocol
inet addr:192.168.8.101 P-t-P:192.168.8.100 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
RX packets:43 errors:0 dropped:0 overruns:0 frame:0
TX packets:26 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:5492 (5.3 KB) TX bytes:5835 (5.6 KB)
11. IP 192.168.8.101 is your PC, IP 192.168.8.100 your phone. Now let's create a new connection profile
on your phone :Setup, Data Network, New, Profile name:ENET2, APN:cmwa, Primary gateway IP:192.168.8.101, Port:0
12. Now you need to setup iptables on your PC. the command you need to write on your terminal is : iptables -t nat -A POSTROUTING -s 192.168.8.0/24 -j MASQUERADE (you need to be root!)
then you need to activated ipforward with this command: echo "1" > /proc/sys/net/ipv4/ip_forward (you need to be root!)
once you enabled ip_forward, you can check it with : cat /proc/sys/net/ipv4/ip_forward if the response is "1" than it's OK.
13. OK now you can open your browser on your phone and connect using the new ENET2 connection-profile.
OK that's all, i have this checked with ubuntu 7.10 and it works very well.
Bye
