Just yesterday, we told you Apple’s iPad would very likely be announced on March 7, and that it would ship with an improved processor and LTE capabilities. Now, a report from The Wall Street Journal notes that both AT&T and Verizon will offer a 4G iPad 3 once the device becomes available, presumably in March.

The report notes that:

Verizon Wireless and AT&T Inc. will sell a version of the coming iPad that runs on their newest fourth-generation wireless networks, according to people familiar with the matter, as the battle to cash in on big investments in mobile broadband heats up.

However, whether other carriers will support the purported LTE-capable iPad 3 remains to be seen, as both Sprint and T-Mobile refused to comment on the matter.

Interestingly, back in June, 2011 a report claimed that the iPad 3 would be AT&T’s first LTE iOS device. Since, shipments of LTE-enabled micro-SIMs have recently arrived at AT&T retail stores, suggesting that a new 4G mobile device, carried by AT&T, is set to launch in the immediate future.

Besides support for LTE, rumors claim Apple’s iPad 3 will indeed include an improved (potentially quad-core) processor, alongside altered cameras and a Retina display. Though as of this moment, nothing has been announced by Apple, meaning we’re all still in the dark.

Here’s hoping the product is announced soon! Feel free to share your thoughts regarding the iPad 3 in the comments.
