iPhone exclusivity fading away worldwide. When will we get a T-Mobile USA iPhone with UMA?

Slowly but surely, the iPhone initial exclusive deals with select carriers around the world is fading away. Carriers have taken notice that an iPhone deal will boost their data usage (and their bottom-line), and for Apple, it’s a logical step to grab market share more rapidly than waiting (or hoping) that users will switch networks. Apple needs this to keep the pace at which iPhone has been growing.

Abroad, Orange UK will launch the iPhone soon, followed by 3 and Vodaphone. In Canada, Bell and Tellus will get it too as Rogers loses its exclusivity, reports itrafik (in French).

Because there’s no CDMA handset in sight (the recent Verizon pokes at the iPhone would indicate that), T-Mobile USA would be the only suitable candidate for an expansion in the US. I would love to see an iPhone 3GS with UMA (hotspot@home) capabilities. Is T-Mobile ready for this? Will it happen soon? I don’t know – what do you think?
