I wanted to know if there were any of these available for GSM sim cards. Like a usb stick, but can be used separately with wifi only connection. I could connect several devices to this one device.

The other option is to buy a cheap android phone with 2.2 installed and use the reverse wifi option to tether the phone. I want 850 frequency for TrueMove 3G, but the other 2, 900 and 2100 are welcome also.

Any ideas?

There have been several threads on this subject so a search might yield more information. I believe there are quite a few Huawei MiFi models available, just make sure you get one with the required frequencies.
