Apple Thoughts: Is There a Stealth Recall for iPhone 4s?

"Yesterday, a reader claimed that-after exchanging his iPhone 4-he couldn't reproduce the sharp signal drop caused by the antenna problem. Now, some readers have confirmed the story. However, others haven't seen any improvement in their replacement units."

From the thread, the reader told Apple that it was because his data was downloading very slow and they exchanged his iPhone 4. Once he got the new one, his problems went away. This was the same story for several responding in the thread so I suppose, if you are having similar issues, this may be one way to fix it. But if this is truly the case, it should be an official return/exchange issue for those having the problem. I wouldn't go as far as a complete recall of every single one of the +2 million iPhone 4s sold (mine is working fine), but it's definitely worth looking into an exchange policy, especially if the reports of problem solved with an exchange are true.
