If you’ve been having a problem with your new Lumia 900, rest assured you aren’t holding it wrong.

Nokia tonight responded to complaints about its new flagship Windows Phone in the U.S. and acknowledged that a memory management problem in the software is causing some users to lose data connectivity, preventing them from browsing the web.

The mobile phone maker says will be rolling out a software update to fix the problem on or around next Monday, April 16.

Nokia also promises a $100 credit to anyone who has already purchased one of the Microsoft-powered devices or does before April 21. That’s the same as the price of the phone itself under a two-year contract on AT&T.

As an alternative to the software update, Nokia says Lumia 900 users can swap out their current phones for an updated one.

“In short, a memory management issue was discovered that could, in some cases, lead to loss of data connectivity. This issue is purely in the phone software, and is not related to either phone hardware or the network itself,” says Nokia in its blog post. “As a proactive and prudent measure, we decided to take immediate action. We have identified the issue, and have developed a solution.”

People posting about the problem on Nokia’s support site said they were initially able to connect to the web with their new devices  but then lost connectivity.

Microsoft and Nokia are banking on the Lumia 900 to help reverse Windows Phone’s fortunes in the U.S. and make the platform a viable No. 3 behind iPhone and Android.
