upgrading to TANGO with Zune...
DVP 16 GB No-Brand Italy

Updated done! no problem...
tethering NOT present, I hoped because with Tango it is introduced in Nokia Lumia 800...

And for peeps like me without a non-branded DVP, here's for sending them cabs to force update to Tango:

No update for me yet and I have an unbranded AT&T compatible version.

OOps my bad. Repeat post. Please delete mods.

To be clear, when we say "unbranded" are we talking about a phone without a logo on it? Or a phone that doesn't come with the AT&T apps that install at the last stage of setup? I don't think any of the DVPs had a logo on them, and to my understanding, if the phone was ever locked to a carrier, you have to abide by that carrier's update schedule (*excluding hacks of course.)

Is that wrong?

Yeah no AT&T apps, not sold subsidized, 16GB unlocked version with AT&T compatible bands. I was able to get the Mango update right away by doing the network disconnection trick.

I think I'll just send the cabs over.

The only physically branded devices dell made recently was the Streak7 on tmo, besides that they never had any external markings or even a custom carrier box.
(The S7 had a single tmo label on the back and that was it)

The rest is more or less correct though, carrier branded = carrier apps + carrier schedule.

Tmo initally had a good relationship with dell (launch partners for the S7 and VP) but then it went south and they blocked the HC update for the S7 and 7740+ for the VP.
