Yesterday we wrote about how the Nokia Lumia 900 had a glitch that caused people issues when trying to connect to the Internet. Nokia U.S. chief Chris Weber said that this was a memory management issue with the phone software and is not related to the hardware. The issue only affected a limited number of customers and they have created a software fix. Customers can swap their flawed phones at AT&T stores for an updated one and there will be a software update on April 16th. AT&T is also offering a $100 credit to customers regardless of whether they had the problem. The $100 credit is being offered to people that buy a Lumia 900 before April 21st at midnight.
