[Gta04-owner] 3G internet connection

Hello Radek,

I now tried the following:

- Power on the phone. After entering PIN I get a black "G" displayed.
- ssh into the phone and execute:  echo "AT_OPSYS=1" > /dev/ttyHS_Modem
- Within Qtmoko choose "Settings" / "Internet" / "Start".

Result: I get "Pending" and then nothing anymore. No reaction to "Stop" 
or anything else. Have to powercycle the phone.

After powercycle I tried another workflow:

- Entering PIN, then get black "G" displayed.
- Within Qtmoko choose "Settings" / "Internet" / "Start". After that I 
get a white "G" displayed.
- ssh into the phone and execute:  echo "AT_OPSYS=1" > /dev/ttyHS_Modem
- Browse some page from the net.

Result: Works, but as slow as it already was before.

What do you recommend what I should try, now?

Best regards
