Modem supporting location information?

[Bastien Nocera <hadess hadess net>]

Heya,

I'm interested in getting a 3G modem that would support A-GPS. I have a
(possibly simlocked) option modem:
0af0:6971 Option Globetrotter HSDPA Modem

Which tells me that it doesn't support Location services. Does it not
support it, or is it not implemented?

I also have a Huawei E585 modem, which doesn't support switching to USB
mode when plugged in, but apparently support A-GPS. If we can make this
work, it would save me buying a new dongle.

Otherwise, I'm in the market for a 3G modem that supports those. Cheaper
is better. Anything on eBay or Amazon that people would recommend?

Cheers
