After discovering that Apple had registered iSlate.com in late 2006 (we dug a little deeper and found trademarks had been filed for 'ISLATE' in both the United States and Europe by a company that was most likely a dummy corporation set up by Apple), MacRumors has now discovered another possible name for the upcoming Apple tablet. MacRumors bases its report on the filing for a US trademark for 'IGUIDE' by another Delaware-registered company called iGuide Media LLC, which can be linked to Cupertino by means of signatures on the documents coming from Apple's Senior Trademark Specialist, Regina Porter. Let's dig a little deeper, once again.
