3G data speed on iPhone 4 is painfully slow

Is anyone experiencing a real slowness in the 3G data speed on the iPhone 4? I had a friend race me to a website with a 3GS, and hers blew mine away. I'm even getting some disconnects when I try to hit a webpage... my friends with 3G's and 3GS's are fine...

iPhone 4, iOS 4, Macbook Pro

Maybe my entire neighborhood is in a 3G data ditch of some kind with signals blocked by surrounding 3 story houses? But the carrier signal is showing 5 bar strength throughout my house.

Is it possible for the 3G data to be slowed down by a weak signal that isn't reflected in the carrier bars?

The reason I ask is that I tested up on the 3rd floor of my house. It's the same 5 bar there, but a 3G speednet.net test shows I'm getting 2.23 Mbps download and 0.97 Mbps upload. Still not near the maximum rating, but definitely tolerable.

Weird. Now I'm getting 2.38 Mbps download and 1.02 Mbps upload even here in my 2nd floor office. I wonder if SoftBank tweaked something after I called them.

This is after days of getting almost no speed on 3G from this same spot.

And now the speed has dropped down to glacially slow again. I wonder what's happening.

I have the exact same problem although... I switch to Edge and it is faster than 3G 🙂 I hate to pay for a phone that doesn't work as expected.

I do not experience any problems with 3G speeds on my iPhone4. Suggest, however, you use a site like testmyiphone to clock it properly.

Is anyone else still having this problem? I always have this problem at the Phoenix airport, and oftentimes at crowded places like malls. Today I was in the Honolulu mall and could barely load my email.

Try clearing temporary files to do this go to settings, go to the safari tab and clear history cookies and cache. This will improve the speed tremendously.

My 4s 3g speed is 10x slower than my 3gs i remember and its still being advertised....

Call it better, faster and even more worldly.

iPhone 4S is the first phone to intelligently switch between two antennas to transmit and receive, so call quality is better. It also doubles the maximum HSDPA data speeds to 14.4 Mbps.⁸ Which means faster connections, faster loading and reloading, and faster downloads.

My speed tests come back at under 500k a time NOWHERE NEAR 14.4Mbps!

Do these even get looked at?

So.ya..i to also noticed my slow speed as well and on day I received a automated text from AT&T sat I was useing way to much data( iam grandfathered in already for unlimited data,) so I called and yes they put a data cap on me for a month ( being punished) lol, slower speed, ) the network giant strikes again, so yes we have unlimited data but loophole is that they have the right to adjust speeds

I have an iPhone 4 and it's also extremely slow. It took me 3 hours to update the facebook app using my 3g data. Apps crash all the time and many websites won't open. My old phone was a Motorola X and it was nearly twice as fast, a third the price, and overall better at everything (except the camera) and I hear it's not even a very good phone compared to most. Just saying...
