Apple iPhone 3G reception problems

More and more people are complaining on Apple's customer support forum about the new iPhone model's 3G network features. According to these complaints iPhone 3G doesn't see a 3G network where other handsets do, calls and transfers get disconnected frequently and sometimes the handset uses EDGE network even if there is full 3G coverage. According to experts at Nomura the solution to this problem won't be simple at all, as they think that the cause of the problem is the chipset and the protocol stack used, so a software update won't have very good results. No matter how it will be, according to Engadget, Apple is already working hard on correcting the error, which will probably be available soon as a new firmware version. So the cause of the error is not the poor coverage of AT&T or other networks. Apple had no official statement regarding the issue.
