HSDPA connexion for the dummies ?

["Joel Carnat" <joel%carnat.net@localhost>]

Hello,

Does anyone wrote down documentation (for dummies ;) on howto access
Internet using an USB HSDPA (HUAWEI E220, recognised by dmesg) modem on
NetBSD ?

I'm running 5.0_BETA/i386.

I found a few articles but can't completely succeed.
The NetBSD gprs.html documentation refers to file to be completed that
don't exist on my system (either in the described ath or share/examples).

I'm quite confused.

TIA,
     Jo
