When my HTC Desire boots, I can first see a purple Android (?) icon, then a white background and the 'HTC' text, then a short animation with text 'T-Mobile'. Does that mean that I got a branded phone? The rest of the system doesn't show any signs of T-Mobile and I'm on a Vodafone prepaid 'contract'.
I'm worried that I got a branded phone (which means I'll get Froyo later than other HTC Desire owners) even though I'm not with T-Mobile.
