According to the latest report from the International Data Corporation, Samsung has ousted both Apple and Nokia to aquire the top spot in both smartphone and total mobile phone shipments for the first quarter of 2012. This marks the first time since the inception of IDC’s Mobile Phone Tracker that Nokia did not lead the global market in total mobile phone shipments. That’s quite a testament to Samsung’s tremendous growth over the past year, which according to the IDC, was nearly triple in the smartphone category.

Today the International Data Corporation raised its 2012 tablet forecast to 106.1 million units, up from its previous forecast of 87.7 million units thanks to a stronger-than-expected 2011 finish. According to IDC, tablet shipments rose 155%, leading to a full-year 2011 total of 68.7 million units shipped. The IDC credits Amazon for raising consumers’ awareness of the tablet category in 2011 thanks to their popular $199 Kindle Fire.
