Apple said to be working on removing limit
An unofficial 500-app limit exists in the current iOS 6 beta, a small consulting firm says. The company claims to have confirmed the cap with Apple. Beyond that limit, users will allegedly start experiencing slow boots, automatic reboots, and other problems. At 1,000 apps, devices are said to fail to boot entirely, forcing owners to restore them.
When the issue was brought up, Apple is said to have asked who would need that many apps. After "many discussions" though, according to Mid Atlantic Consulting, Apple is said to have conceded the point, and promised a fix at some point in the future, possibly in the next beta.
Any limit would be a backtrack from iOS 5. The only code restriction in that firmware is the number of apps a person can fit into folders and homescreens, which is several times the iOS 6 limit. Practically, though, a device would likely run out of flash storage well before hitting any software barriers.
