AT&T Losing iPhone Exclusivity on Wednesday?

HotHardware claims that AT&T may be losing its iPhone exclusivity as early as Wednesday at Apple's media event:

According to an inside source close to the going-ons involved in all of this, a new tablet of some sort may not be the only thing on deck for next Wednesday though. We have been led to believe by an inside source that AT&T will lose their iPhone exclusivity on the same day, though it's not yet clear what other carrier (or carriers) will be stepping in to also carry the phone

We've never reported on a rumor from HotHardware before, so we have no record of the accuracy of their sources. That said, AT&T exclusivity has been a hot topic ever since the iPhone was released. In the U.S., AT&T remains the only mobile phone carrier that offers the iPhone.

This deal has been rumored to be expiring in mid 2010 with indications that Apple has been working on a Verizon-compatible iPhone. While the announcement of a Verizon-compatible iPhone certainly seems possible this year, we're not sure how it would fit in with what is believed to be an event focused on the new Apple Tablet.
