So I went to a t-mobile store today to pick up a MT4G, and noticed that the demo handset had wireless tethering enabled. So, I went ahead and bought one on my Even More Plus plan (installments, not subsidized/contract.)
Once I got it set up and working, I had a look in the Wireless settings again, and....vanilla Froyo tethering is enabled?!?
Now, I'm sure they plan on handing this similar to the T-Mobile TV stuff (trialware with a big fat agreement before you can run it) - but why would this be enabled out of the box? They can't charge you without you agreeing to the extra fee.
Now, apparently there's an OTA already, but I'll be damned if I'll install until someone confirms that tethering still works without an up-sale screen.
Anyone have any insight on this? Why is this enabled without me having to agree to paying the bill?
