The Samsung Galaxy S3, despite its detractors, proved to be a pretty popular phone. Despite many complaining about some of its hardware, design, software, etc, there were just as many who flocked to the pre-order pages the minute they went live. Well as it turns out, the Galaxy S3 might be so popular to the point where AT&T could be facing some shipping delays when it comes to the device. According to the AT&T forums (source link below), it has been reported that those who placed their pre-orders are being sent emails notifying them that, “Due to manufacturer supply constraints, your new smartphone will now arrive no later than Monday, June 25th.” At the same time there have been reports that some orders have shipped, but based on the majority of the comments, many AT&T subscribers are facing delays. To our AT&T readers out there who pre-order the Galaxy S3, have you received the email stated above as well, or have you received your device already?
