Reports are coming in from users who have either unlocked or Jailbroke their iPhones that Push Notification fails on their device.

Czech iPhone developer, PoweryBase, believes that Apple is blocking Push Notification on iPhones it has not explicitly authorized. The news comes after users who Jailbroke their iPhones were having problems with Push Notification as well. However, a fix has been found and will be released by the iPhone Dev Team.

“We’ve received hundreds of support request in the last few days since NotifyMe appeared on the App Store. Unfortunately, about 80% of them are from the users with unlocked iPhones. They’ve bought the application and are mostly angry, sad or hopeless and the worst part is that we can’t really help them. Push simply does not work reliably or does not work at all on any unlocked device, no matter what Push application is used. We understand that unlocked iPhones break Apple’s and carriers’ bussiness and there isn’t really a way to fight against it.”
