I'm curious to see if others have had the same issues that I've been having.

I updated my iPhone 3GS to version 4.1, and updated the iPad to the latest version that iTunes would let me download, version 3.2.2

After the iPhone update, I've had terrible 3G service, in areas that I've always had excellent coverage. I have also had multiple dropped calls. With the new iPad update, I've still had the same service quality.

As I type this message, I've only got 2 bars of 3G on the iPhone, but full coverage on the iPad.

Apple said that it couldn't possibly be the update, and that it was probably the phone. However, I've noticed co-workers and friends that are having the same issues.

Any ideas as to what it could be?
