The iOS 5 beta causes some first-generation iPads to overheat, it has been claimed.

PC Pro reports that a reader was told by a member of staff at the Apple Store in London's Regent Street that it was a known issue after he took his first-generation iPad there to report overheating problems he had encountered immediately after installing the iOS 5 beta.

According to the report, the Wi-Fi chip on the affected iPad stopped working and the screen temperature reached 65 degrees celcius. The owner was initially refused any compensation but staff at the store ultimately offered him a replacement as well as £60 of App Store vouchers.

Apple declined to comment on the story.
