Sprint has confirmed that they're running a “little behind” on deliveries of the Galaxy S III due to the phone's “overwhelming demand and limited supply.” Sprint expects to deliver the 16GB Galaxy S III pre-order by this week and will sell the 16GB version from tomorrow through web and telesales, while reaching retail stores next week. Pre-orders of 32GB variant will be fulfilled by next week.
On the other hand, T-Mobile will limit the launch tomorrow to top 29 markets and will expand the availability by next week.
