From the looks of it all, this whole thing came about after HTC was found guilty of infringing on a patent from Apple last year. Soon afterwards, the US International Trade Commission went ahead and ruled that future imports of devices deemed as the offenders are to be totally barred from being sold. In fact, that specific order actually went into effect on April 19th, so HTC’s newest babies are going to be feeling the heat from all of it. HTC said in the statement:
So there you have it folks! It makes us all wonder if this whole thing had something to do with the recent sold out status of the HTC One X over at AT&T, but more importantly, we’re curious to know how this will affect the pending launch of the HTC EVO 4G LTE for Sprint. We’ve reached out to HTC for additional details regarding the matter.
