GTA01 battery charge circuit: ID pin?

[Major A]

Hi,

I have a GTA01 and want to use it even when I don't carry a computer
with me. I read that the battery charge circuit of the GTA02 will
switch to high current if a 48k resistor is present between the
mini-USB ID pin and ground. Does this also apply to the GTA01, i.e.,
is it worth hacking up a cable for that model?

Thanks,

  Andras
