I honestly don't know why Apple's product launches attract so much rumour and speculation, but it doesn't seem like it is a trend that will die out any time soon. Of course, when the product in question is the iPhone it only tends to make things worse, so here we go again. When the iPhone was originally launched last year some expressed disappointment that 3G compatibility wasn't included and have likely been waiting for an updated model ever since. A recently leaked AT&T memo suggests that they may not have to wait for too much longer, as it requests employees not take vacation time between 15th June and 15th July due to "an exciting Summer Promotional Launch". If it does happen to be a 3G iPhone, it would likely put the launch date close to the one year anniversary of the original release on the 29th June.
