Ah, AT&T…you always manage to find new ways to suck. According to several MacRumors forum users, AT&T is capping upload speeds at 100kbps. According to the posters:
Cities/Regions affected so far: NYC, Central Jersey, Boston, Orlando, Seattle, South Jersey/Philly, Columbus, Cleveland, West Houston, Phoenix, Northern Colorado, St. Paul/Minesota, Suffolk County/Long Island, Quad Cities, South Jersey, Denver, Detroit Metro, Cincinnati, Baltimore, Salt Lake City, Las Vegas, Kansas City, Fairfax, Minneapolis, Washington D.C., Des Moines!
I imagine there are thousands of iPhone 4 customers with expensive new hardware and contracts that are really pissed off with their upload speeds. If you happen to live in one of the regions mentioned above, kindly run a speed test and let me know if you’re being capped by AT&T.
I don't live round there but currently, with 5 bars of 3G,
407 kbps DOWN
208 kbps UP
Emailed you my test.
