Less than a week following the release of iOS 8, Apple has released the first update to the platform.
Within an hour-and-a-half of it going live, Apple is said to have pulled the update. The update, which was meant to bring new fixes to the latest software, brought more problems than it solved.
Hundreds on Twitter said they are unable to get a cellular signal following the update, with their iPhones stuck in searching for service mode, or getting the "No signal" message.
Others are seeing problems with the Touch ID fingerprint reader after applying the 8.0.1 update.
We tested an iPhone 6 running T-Mobile in ZDNet's New York newsroom, and an iPhone 6 Plus running on the 3 network in the UK and can confirm the cell service and Touch ID issues.
Several iPads that have been tested however seem to have survived the update unscathed. Also, we are getting unconfirmed reports that the problem is confined to the iPhone 6 and iPhone 6 Plus.
An Apple spokesperson said "we have received reports of an issue with the iOS 8.0.1 update. We are actively investigating these reports and will provide information as quickly as we can. In the meantime we have pulled back the iOS 8.0.1 update."
An unofficial fix for this issue is outlined, which involved rolling back to iOS 8.0.
There's no mention as to whether the update brings with it better battery life or fixes some of the stability issues that some users have been experiencing. Also, there is no word as to whether this update includes any security fixes.
iOS 8.0.1 brought updates to HealthKit, and addressed third-party keyboard issues.
Apple is down more than 1 percent on the Nasdaq in mid-afternoon trading.
