The phone's radio problems can't be solved with a software fix, no matter what Apple says. We talk with CNET's Maggie Reardon and AnandTech's Brian Klug about what's really wrong with the iPhone 4.
The iPhone 4's radio woes are well-documented. The most recent tests,, show dramatic radio performance issues when a part of the external antenna is gripped.
This week on the Roundtable, we delve into the electronic and radio engineering issues affecting the iPhone 4's antennas, as well as other phones. Our guests are CNET's Maggie Reardon, author of ," and AnandTech's Brian Klug, who tested the iPhone for that site and co-wrote "Apple's iPhone 4: Thoroughly Reviewed."

Let's talk about networks. You can have five bars and still get dropped calls or slow data. How?
Questions from the chat room:
rygavs: Are the radios on the iPhones that have been already sold easily repairable without a bumper? Could Genius Bar staff just coat it with something?
CurtisB: Is there a difference in reception between Edge and 3G?
TBolt: I'd be curious to know if the current iPhone would fail on Verizon's network just as much as it does on AT&T's.
