Slow Chip Stifles iPhone 3GS Upload Speeds
At Apples Worldwide Developers Conference, the company proudly boasted that the new iPhone 3GS supports 7.2Mbps High-Speed Downlink Packet Access (HSDPA) a faster, next-generation network standard that many carriers plan to adopt. However, downlink only refers to download speeds; the company made no mention of uplink speeds, or how fast users will be able to upload data.
Thats probably because Apple didnt want anyone to know that the iPhone 3GS contains a 3G chip with a surprisingly low upload speed a Universal Mobile Telecommunications Systemchip High-Speed Downlink Packet Access (UMTS HSDPA) chip, one of the earliest 3G technologies that phones were using years ago, according to Tero Kuittinen, an MKM Partners telecom analyst.
