I just downloaded the 2.1 update for my iPhone 3G. First off, the signal strength went from 1-bar or no-bar before the update, to FIVE bars of 3G signal after the update. That's in the same position, same location, nothing else a factor.
Denver here. Just downloaded and installed 2.1. Reports of the BARS reading higher are confirmed, at least from my observation. My work location was showing barely one bar with a dbm in the -100s. Dbms have not changed, but bars now THREE. Interesting! I also am seeing a faster switch between E and 3G. Will try some calls and see if I can now receive inbound calls at this location. Before, things would go to VM about 70% of the time.
Nothing THAT new trust me mate...
all these new stuff can be done through a Bug fix 2.0.x instead all of this big 2.1
what should be counted under 2.1 is the Genius Playlist, Data Wipe & SMS Notification thing, *JUST AS WHAT WE ASKED FOR*
i really don't see a point in this new Software, i consider it a Bug Fix
ONLY
a little cuestion, my iTouch has 2.0 , and I have the message that a upgrade its available, i hit hte button, but I receive a message that says that I can not connect to the server
