If you're an AT&T customer and have experienced slower than normal data speeds, don't believe the rumors AT&T is about to cap data speeds.  It's also not a result of customers excessively using the new iPhone 4.  Instead, it's a software glitch.

Over the past few days AT&T customers have voiced concerns over plummeting data upload speeds and AT&T is reassuring customers this is not an attempt to place a cap on data speeds or any other conspiracy theories to undermine data usage.  AT&T is even using Facebook and Twitter to help get the message out.

According to AT&T the problem is a software issue which AT&T and it's network partner, Alcatel-Lucent, has identified. The slowdown apparently is only effecting those with Laptop Connect or smartphone customers using 3G HSUPA-capable phones under certain conditions.  The problem is only affecting about 2% of AT&T's wireless customers and is limited to markets with Alcatel-Lucent equipment.

AT&T is implementing a short-term fix that will provide normal 3G speeds to these areas while Alcatel-Lucent works on a long-term fix.
