At least one user paid a visit to the Genius Bar at his local Apple retail store but was told that there are no replacement units available at the moment. Given the iPhone 4 shortages, it may be some time until affected users can obtain replacements.

The prevalence of the issue is unknown at this time, but there are a significant number of users reporting experiencing it on their phones.
