Phone Arena reports that according to a tipster, AT&T retail stores have recently received LTE-compatible micro-SIM cards.
AT&T has notified the retail stores to scrap all old micro-SIM cards and replace them with the new LTE-compatible micro-SIM cards.
This is leading to speculation that iPad 3, which is expected to be unveiled at a special event in the first week of March could support 4G LTE Networks.
According to Phone Arena, one possible reason for the change of micro-SIM cards could be due to the launch of Lumia 900 next month, but they're also speculating that it could be also be meant for Apple's next generation iPhone, which is expected to support 4G LTE networks.


With the launch of iPad 3 next month, it is possible that AT&T is gearing up for it. The 4G LTE support would also explain why it could come with a bigger battery.

The reason we sell LTE micro Sims is because we sell a phone called the Pantech Burst, which uses a LTE microsim.
nice try in throwing people off
except we do sell a phone called the pantech burst and it does use a LTE micro SIM.
its totally plausible that the next iphone could be LTE but this is hardly evidence
Oh Dave u just crushed all the apple fanboys hearts tell em u were just kidding.…
iPad3 won’t be LTE, be reasonable. Look at all the problems LTE is having with batteries, Apple won’t be using it until 2013 since they have already been having battery issues with the iPhone 4S
This is quite a bit of evidence, really because ipad 3 is LTE.
