Are you also in Miami?
This is a discussion on Nexus S: 3G and WiFi Problems within the Nexus S forums, part of the Google Phones category; Are you also in Miami?...
I just saw at the t-mobile store the Samsung Vibrant and its 3G worked fine.
The nexus one is also having the same issue. I talked to tmobile about 10 times already. They don't want to help. Also if you go away from the downtown/miami beach area you get perfect 3g signal. Its definitely a tmobile issue.
I am in the Florida Keys and I have the same problem. Didn't happen in Fort Lauderdale. I also wiped the phone but nothing.
As of today 12/28/10 the 3G disconnect issue has been fixed for me in the downtown area. Seems like T-mobile has been doing some upgrades to the towers here.
Not having these problems here in NY... sorry I cannot help you guys
It has also been fixed today here in South Beach!
Hopefully this will keep working well.
Yes it seems solved also in Florida Keys. Great thank you guys!
Im in boston since a few days.
NO PROBLEMS AT ALL!
seems to be a problem of t-mobile in miami beach
maybe you have to try another carrier there
why not try anther 3g phone going internet with your sim card at same location, it may identify the problem is or not about the NS.
