Can anyone confirm there is a UMTS issues in Arlington, VA? I complained about the iPhone 3G not have very good 3G speed and they stated there is a UMTS issue in this area since 7/16/08.
My issue: Fast speeds for 30 minutes or slow and then time-outs, mega latency, etc... Edge is VERY reliable.
Note: My 881U modem doesn't seem to have any issues in the same area. Other people are experiencing the same thing with the iPhone. Tech stated the 881U uses different 3G technology than the iPhone which doesn't make sense to me, but...
Is it the phone or is there really a network issue?
It is most likely your iphone. A lot of recent reports are stating that the 3G chip in the iphone is a unique design and is failing to perform properly in many units. Apple is supposed to be putting out a software upgrade to help fix this.
