iPhone launching on Swisscom on April 4th?

No one really knows when the iPhone will officially launch on Swisscom, since as far as we know, every rumored release date in the past for the wireless provider has come and past with nary an iPhone to show for it. But yet again, we have another rumored release date, thanks to a Swisscom flyer which was snapped in typical rumor-mongering fashion, which says the iPhone will launch with the provider on April 4th. So they say.
