In the immortal words of Home Simpson - d'oh. Someone over at PayPal hit the go button too early on the official announcement that PayPal was now supporting the Android Marketplace. Apparently, the announcement was only online for a very short time, but that was long enough for it to be Tweeted and Google to cache the page immortalizing someone's mistake.
PayPal's Naveed Anwar was the name attached to the announcement. The announcement also noted that with the addition of Support for Android Marketplace it was on all platforms including iTunes and the Blackberry App World as a payment method.
Presumably, since the post went live and is all ready to go the official announcement will be coming soon. We will keep our eyes peeled.
