The one or two bars bit falls on all cell phones by the way. Including Galaxy S models and supposedly Droid X. The bar drops aren't the real concern, but the call quality and lost calls.
Apple is working feverishly on fixing the call quality and lost calls problem on their iPhone iOS which they would be reporting on progress by September 30th which would be the x.1 date.
-------------------------------------------
Several have reported the static issue which may be contributed to background interference of electronics. Apple may be working on this problem as well, but haven't spoken about an iOS patch. You may succeed on a replacement iPhone.
On a comparison video from Phonedog or PhoneArena on the two models indicated the i4 has static issues and the Galaxy S generated muffling issues.
So you would be choosing either to a hum voice or to a muffled voice.

Sadly Samsung left out any details on transferring files from the device to SD. Note however they are on 2.1. You would not be allowed to transfer until 2.2.

Adding a side note, you should also review the Google News by typing iPhone Android and reviewing the massive issues between both OS devices. Android being wide open to unchecked software can fetch your data easier than iPhone.
