Users Still Getting Frequent Dropped Calls After 2.1 Update (AT&T To Blame?)

Even after the 2.1 software update, some users are continuing to report reception issues on their iPhone 3Gs. While the 2.1 software update technically did claim that it wouldn’t actually boost signal strength but make the signal more accurate. Nonetheless, I saw a noticeable difference in my reception, but some users say that the issue with dropped calls still persists.

Two discussions users from this thread reported:

“the point is that the 3G did go from zero to all the bars but still dropping the calls!

“I just bought my iphone yesterday and asoon as i got home the reception was terribal so i updated it to 2.1 and instead of getting no bars i get 1 to 3 bars but it goes off and on and turns 3g off and goes to edge.”

There is another method for checking your phone’s signal strength by looking at its dB meter. You can access the dB meter by going into field test mode, which is done by dialing Dial 3001#12345# then press “Call.” A dB reading greater than -50 is a good sign. (Note: dB is measured in negative numbers; the closer to zero, the better the signal strength.)

AT&T has admitted that the increase in traffic created by iPhone 3Gs has caused issues in certain areas, resulting in slower network speeds and calls being dropped. They claim to be boosting their infrastructure to cope with the demand.
