No one outside the contract signers at Apple and AT&T know for sure when US iPhone exclusivity ends, but HotHardware is stirring up a storm with the rumor that it ends this Wednesday, at Apple's "Come see our latest creation" 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


Inside of AT&T, we are hearing that the iPhone is causing more trouble than ever before. On some level, having the iPhone is hurting AT&T's image. Because they are the only company to carry it, and it's such a data hog, it's largely to blame for AT&T's network troubles. [...] The iPhone itself doesn't really handle the switch from 3G to EDGE very well, so calls that are in-progress tend to fail whenever the 3G bands aren't optimal and the phone attempts to step down to EDGE.

They claim AT&T is tired of the bad press and will let other networks share the burden while AT&T introduces new phones from other platforms (hello Android and webOS?) in order to compete.

The follow on rumor, of course and as always, is that Verizon will then start to carry a CDMA-friendly version of the iPhone 3GS and the new iTablet.

No comment from AT&T yet, but anyone buying this?
