At launch, AT&T and Verizon will be the exclusive carriers of the new 4G-enabled iPad in the United States. In the spring, however, Sprint will also be launching its own 4G LTE network. With the carrier already selling Apple’s flagship smartphone, users were shocked to see the Cupertino-based company shun its new partner’s network — but this may not be the case. According to images obtained by Engadget, Sprint iPad models have begun to show up in Best Buy’s inventory system. Nothing is confirmed at this point, but it is possible that a Sprint iPad could launch around the same time as the carrier’s first batch of 4G LTE smartphones. A second image of Best Buy’s system can be seen after the break.
