3G dongles...

[garbagecanman]

So i was wondering about setting up 3G and which dongle to use. My device says it supports the huawei dongles under 3g settings. I would need one that works with my att sim card? These are the ones shown under 3G settings.

Huawei E220, 230, 169, 160x and 1750 for WCDMA I googles and it looks like the E220 and one of the other ones support att i think?

So which dongle should i get?

Thanks
