What are the options for connecting laptop to T-Mobile's 3G?

[naviger]

I have T-Mobile's "Total Internet for Data Cards" plan and am able to connect my laptop on 2G using a Sierra Wireless AirCard 881, which unfortunately is incompatible with T-Mobile's 3G data band.

After studying the forums here it's still not clear how to connect a laptop computer to T-Mobile's 3G. Apparently some people tether to an SE TM506, but maybe some TM506 models need a firmware change to enable tethering. T-Mobile support told me that some phones support tethering but none at 3G speeds.

Also mentioned here in the forums; a type of data card from option.com, the Option GT 307. Regrettably, the option.com web site doesn't mention the GT 307.

What are the best known methods, and approximate prices of the hardware, for connecting a laptop to T-Mobile's 3G network?

1) TM506 build date before 9/8
2) Bandrich C105.. order from Stelera.. search for other thread
3) Expensive and rare GT307.. search for this one also
4) Nokia 6263 and Nokia 3555 ... at UMTS speed..
5) Upcoming Pharos 137.. at 600 $ price tag

Thanks for the helpful details. I like the features of the GlobeSurfer_III but due to it's $400 price tag I will be using one of the lower cost solutions.

Is the Bandrich C105 Mac OSX compatible? And how does it hold up for 3G speeds? I'm searching for an aircard that has it's own processing unit so I don't take a hit on performance on my new S10 netbook.

the GSIII (312) passed FCC, with ALL US 3G bands
