No/super slow Data in Downtown Chicago...

What has everyone's experience with data been like downtown?

Here's my backstory- I got the i4 Friday morning. My office is at Madison and Clark. I had 5 bars and the 3G icon was on. Data was beyond slow. Couldn't even get the app store to load. Emails took minutes to load rather than seconds, safari was useless. Went back to ATT store, they tried swapping the sim card, still no luck. Took the el home to Lakeview, and as I'm riding, suddenly my i4 is in hyperdrive. Everything is lightning fast. I downloaded like 8 apps just on my 20 minute train ride. email, FB, and everything worked great. Same thing all weekend, so I chalked up Friday's peformance to a fluke.

Get to work this morning and back to square 1. Super slow email. Speed Test app can't even identify a server. Still show 5 bars and 3G connection though.

I upgraded from a 2G iPhone, so I don't have any experience with the 3G network. Is it just worthless in the Loop or is something wrong with my phone? The guys at ATT said I could exchange (once they have more in stock). Just wondering if that is the problem or if it's something else.

Thanks!

I'm currently sitting in the West Loop near Washington and Morgan. I've got 3 bars of AT&T 3G coverage on my iPhone 4 and my speed is 2365kbps down/1004 kbps up. Not too bad, certainly usable.

Thanks. I should add that the ATT employees had good service on their 3GS's, so it's almost like my phone just doesn't like downtown. I really am at a loss.

AT&T is currently upgrading a ton of towers and also adding tunnel service in the loop. Im a little outside of the loop and my speed was HORRIBLE on Friday. I chalked it up to them possibly working on the network at that time. I went to the Crosstown classic yesterday and my reception was super fast while on my way there in the loop as well as at the game.... which sucked... LOL Sox fan here

Are you still having slow speeds today? Is it only in your building? Make sure you arent grabbing someone's free wifi also. I usually shut my wifi off when Im not on it.

Yeah, it's still bad. It was bad across the street at the ATT store too (where you know they make sure to have a good signal) and walking around outside. WIFI is off. Like I said, I have 5 bars and the 3G icon showing, so it's not like I'm in a dead spot. for some reason my phone just won't work right.

Cubs fan here- one win in a season of crap doesn't really do much for me though. We need a streak like the Sox just had.

Which building? I used to work in 20 N Clark.

Anyway, I left Chicago a few months back, but I always had good 3G coverage at my office, and at my condo in the River North/Gold Coast area. I had an iPhone 3G, and later a 3GS.

The Chase Tower- 21 S. Clark (or 10 N. dearborn)

I think I'm definitely going to go for the exchange if ATT can hold one for me tomorrow. I have a 6pm Genius bar appt tonight too- maybe they'll have a replacement in stock for me.

Yeah, that was a nice run! But 12 in a row wouldve been much nicer! Great series though, as usual. Aside from Big Z almost going at it with DLee!

Not sure about your signal though, thats weird. Does anyone else in your building have an iP4? You could do a side by side, you might have a bum radio or something bizarre like that.

No one that I know of. Maybe I'll go stand in the lobby and stalk people.

Big Z- don't get me started. Bad enough his skills are deteriorating, now his already fragile brain is slipping too...

Not in Chicago, but I'm having the same experience. 5 bars and the 3G symbol. Latency/Ping times swing from 180ms to 25000ms (most over 10000) and my download speeds are swinging from 5 to 3500. Upload is worse, only getting 0 to 500. I've seen this thing work, but it's horribly unreliable. When it does work though, it blows my old 3GS away. But the other day we were in the car and my wife's surfing on her 3GS, I'm showing 5 bars and 3G, but just getting a spinning flower. Really getting frustrated. Let us know what the genius bar tells you. I may have to go and look for an exchange as well.

Oh yeah, and this is with the phone sitting on my desk or in my hand. Though I have seen the signal strength drop from holding it if I don't have a strong signal. Earlier trying to pull up web pages I would either get server not responding or "unable to process raw data"

OK- I'll post back tonight/tomorrow morning. I should add that it's also draining my battery since it's spinning it's wheels all day.

I'm at Monroe and Dearborn. My cell service is always crap even though I am right next to a window on the 19th floor. I didn't expect the iP4 to be any better.

I could see it being bad in my office, but in the ATT Store is what makes me wonder.

Just walked over to the ATT Store. Once I got outside, everything worked fine again. At the store it was a little slow, but comparable to the demo i4 there. Rep gave me a spiel about congestion and big buildings, plus the Taste of Chicago going on. We agreed that I'd give it a week and see how everything was. Not going to bother with the Genius Bar for now.
