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

Yes. I would call att. I had this issue and way very annoyed. When I called AT&T they checked on the network in
My area and were able to tell me that the problem was with some of their towers. When they fixed them, I have been getting faster 3G speeds
Than I ever did on my last iPhone (the first 3G).

I saw a definite issue on Friday in the Allentown, PA area. Here's my story: Started off at work. I went to show some folks how cool the new iPhone 4 is. Popped up Safari and nada...pages would not load. Rebooted. Still not working. Tried all day. No luck. After work, drove about 10 miles to an AT&T store. I showed a store employee the problem. She pulled out her 3GS and we both loaded the same page, PayPal, and her's same right up and mine took several minutes. AT&T reps said "let's replace the SIM card." Did that, loaded PayPal just fine and walked out. I went across the street to eat and shop a nearby Apple store to look at cases. After dinner, I went to pull up a Web page and the same problem as before. Walked next door to the Apple store. I turned off the WiFi on three different iphone 4s on display and had he same issue. 3-5 minutes to load pages including panasonic.com, samsung.com, and sanyo.com (I tried to use non-mobile pages that probably aren't cached on the device). I asked the Apple store employee standing next to the iPhones and he explained it as likely a 3G connectivity issue in building - odd given the phone were showing around 4 bars. These phones were in the stands so it had nothing to do with how the devices were being held. Took my issue to the Apple Care counter to open a ticket. Three other techs pulled out their iphone 4s and confirmed the issue and also blamed it on the network. I asked them to try the same thing on a non iOS 4.0 device and, while they had trouble locating one at first, they did manage to find a 3GS with iOS 3.1.3. PayPal.com loaded right up on the same 3G network which was at an utter stand-still for our iPhone 4 phones. Other pages also loaded fine for the 3GS. Apple Care tried resetting my phone to factory defaults - no change. I have no explanation for this and did not have problems once I got home about 20 miles away. In fact, at home I'm typically on Edge and was amazed at the excellent coverage and blazing fast data speeds I was getting at home on my iPhone 4 over the 3G network.

I have been having 3G issues as well. I was in our local Target store, where my 3GS would always lose signal entirely, and was shocked to see 4 bars and 3G availability. But when I tried to access the internet, I could not make a connection anywhere.

I ran some speed tests while I was running errands in South Jersey, and sometimes my speed was so fast it was unbelievable, and then a half mile later in another parking lot it was a fraction of the previous speed and/or I would be unable to make any connection whatsover.

Hopefully, it's just all the iphone activations combined with the nasty storms we had out here.

I have had my iPhone 4 since launch day. Funny thing is, I didn't notice the data issue until yesterday, because I have been using WiFi since the phone was activated.

The issue was noticed at a local mall in Ann Arbor, MI. I could NOT access email, or get updates for any apps. Ran some speed tests, and noticed that 3G data was pretty much not working. When I switched to Edge, it was the same story. No data.

I pulled out my 3GS (it's my wife's now), and 3G worked perfectly. No issues. Put both phones on a table right next to each other. iPhone 4 - no go. 3GS, perfect data rate and quality. Signal strength was 4-5 bars at all times.

Next, I went to the Apple store that is in the mall. I shut off WiFi on one of their display phones, and started testing it. EXACT SAME ISSUE. Their brand new iPhone 4 sitting in the display couldn't download any data, despite the perfect AT&T 3G signal in the store!

I asked an Apple Genius about the issue, and he told me his personal phone has the same issue, and that apparently Apple is aware of the issue. It's interesting, because he didn't sound too concerned with the issue.

At many points throughout the day, I continued to randomly test the iPhone 4's ability to pull data. At some times, it would be amazingly fast (4000 down, 1500 up or so), and then, it would slow to a crawl and stop alltogether.

My theory is that AT&T has the iPhone 4 segmented onto a different data pipe versus their other devices, and that they are experiencing issues with this new pipe. I live in a very rural area, so the issue isn't one of local congestion. Rather, probably a backbone issue.

I just noticed a potential fix for my iphone4. I've been having painfully slow data connections over 3G, but when I killed all of the apps that access data (mail, Pandora, etc) and only used one or two data apps, the 3G speed kicked in. I wonder if having several data apps open is prohibiting the data from throttling to the correct app.....

I'm having this issue as well. I'm in Northern Va but was in Allentown PA over the weekend and have seen the problem in both places.

I have the speedtest,net app and I can run the test with the phone in the exact same spot and get anywhere from 0Kbps downloads to 2Mbps downloads. The 3G bars fluctuate all over the place from full bars to no bars.

Toggling Airplane mode seems to restore my 3G connection data speeds to normal temporarily but ultimately it degrades back to nothing,

Hopefully it's the rumored software problem that there may be a fix for soon otherwise I'm going to have to return the phone and go back to my old phone.
