That's what the rumor mill has churned up. The rumors and speculation around Apple products have always been wild and inaccurate. However, sometimes a true leak makes it out and people go crazy. Someone who claims to be an AT&T employee has tipped off Gizmodo stating all vacation will be denied for the end of September. AT&T has done this previously when new iPhones have launched, so it's highly likely that this is true.
One rumor I keep seeing is that the iPhone 5 will be redesigned to sport a larger, higher resolution screen that goes all the way to the edge. To support this there have been unconfirmed iPhone 5 cases spotted all throughout China that point to a thinner and slightly larger iPhone 5. Here's a quote below from 9to5 Mac.
"Our new images are clear and there are appears to be a slight – not major – tear drop in the design. The case goes thick to thin from top to bottom. In addition, the sources who provided us with these two new cases have shared some dimensions. According to them, the case is 5 inches tall and 2.8 inches wide. These are tight cases so the iPhone 5 dimensions should only be a few millimeters smaller than those numbers. For comparison, the iPhone 4 is 4.5 inches tall and 2.31 inches wide."
As a current and dissappointed Droid X owner, I have to say I'm ready to get back onto the iPhone bandwagon. If there's one thing I have enjoyed about the Droid X it's the larger screen. So if the rumors are true about the size increase, I'm going to be one happy camper come this Fall.
