Nokia has just confirmed the data connection problems that some early buyers (and reviewers like ourselves) have seen on the Lumia 900, describing it as a "memory management" issue. That's the bad news; the good news, however, is that the company claims that it's strictly a software bug, not a hardware issue or a problem with AT&T's LTE network. New phones with updated software are apparently already on their way to stores — Nokia expects them to arrive within a couple days — and if you don't want to exchange yours for a new one, you'll be able to update your current device using the Zune client on or around next Monday, April 16th.

Regardless, anyone buying a Lumia 900 between launch and midnight on April 21st will qualify for a $100 credit on their AT&T bill, a nice "we're sorry" from Nokia for the trouble (even if the phone isn't in stock, you can get a rain check). If you didn't think this was an absolutely critical launch for these guys, you should now.
