In response to a stirring brou-ha-ha kicked up yesterday, AT&T is attempting to douse a fire regarding iPhones and GoPhone plans before it spreads too far. Also, it looks like AT&T retail stores will have limited supplies of the iPhone 3GS at launch.Earlier today, AT&T tweeted the following: "@ATTNews FYI: AT&T will have limited iPhone 3G S in store 6/19. Preorder, though, for most certainty/convenience."

In other words, if you want an iPhone on launch day, you should have pre-ordered by June 13. If you pre-order now, you probably won't be able to get your hands on an iPhone June 19. Instead, it may take one or two weeks before yours becomes available. There is a chance that you can walk into an AT&T or Apple store on June 19 and manage to snag one, but it's not a certainty at all.

In order to combat a possibly damaging wave of negative news, AT&T wants to be clear on GoPhone plans for the iPhone.

According to an AT&T spokesperson, the bottom line is this: The original iPhone from 2007 was/is the only iPhone approved for GoPhone pre-paid service. The iPhone 3G was never qualified for this plan, and neither will the iPhone 3GS. If you think you can get away with registering the iPhone 3GS with your old GoPhone account, it's not going to work.

The full details regarding the iPhone 3GS and its GoPhone pre-paid plans can be read below:

iPhone OS 3.0 Software Update available on June 17 may impact the data service for certain GoPhone customers using either an Original iPhone or iPhone 3G.

AT&T GoPhone rate plans will not be approved for use with iPhone 3G S when the new device becomes available on June 19.
