AT&T not throttling iPhone 4 upload bandwidth

Some iPhone 4 users have experienced slow upload speeds on the AT&T network, but the issue is not a result of intentional bandwidth throttling by the U.S. carrier, AppleInsider has learned.

Users across the U.S. have reported upload speeds of around 100Kbps, well below the capabilities of the HSPA-capable iPhone 4. The issue has affected users in a number of major metropolitan areas across the country, including New York and Los Angeles.

While some speculated the problems were a result of bandwidth throttling by AT&T, that is not said to be the case. Instead, AppleInsider has been led to believe that the issues are a result of an unintentional software glitch related to High-Speed Uplink Packet Access in some sections of the country. When working properly, HSUPA can allow uplink speeds of 5.76Mbit/s.

It is believed that a fix for the issue is forthcoming, though AT&T did not provide a comment on the matter as of Tuesday evening.

It's getting redicilous ATT. A couple of years ago I would have given you a break. Crazy high demand, new 3G service, so on, but at this point your service is a joke and I hope everyone leaves ATT as soon as iPhone goes to any other carrier. ATT is ruining the iPhone experience.

“When working properly, HSUPA Category 6, as found on the iPhone 4, can allow uplink speeds of 5.76Mbit/s”

HSUPA Category 7 will allow for 11.5 Mbit/s and future HSPA+ implementations allow for 22Mbit/s up.

Before going off half-cocked why not wait for some real information to emerge. I know it's the new nerd mantra to bash at&t but you will be depressed and suicidal if you actually think at&t will lose all of its iPhone customers, or even a significant percentage. Not going to happen. Just as the antenna issue is over hyped hysteria by a vocal minority so is this. You won't even get the trolls to agree. They'll swear it's the iPhone doing this and not at&t.
