The SDK for iOS 5 beta 2 has revealed that Apple is planning to enable some over-the-air updates over 3G, while Wi-Fi or 3G connections will be required to download certain alert messages.
These alert messages will provide information related to battery lifetime or storage requirements. The operating system will require a certain battery life and a certain amount of free space to safely perform the update, Electronista reports.
Apple and its carriers might limit the use of 3G updates so as to reduce the use of 3G connections. For example, carriers could drop support for some updates on their cellular networks, while Apple might allow its customers to use 3G connections for minor updates and offer major updates on Wi-Fi only.
It appears that the Chinese market is becoming an ever-increasing priority for Apple since the company is reportedly preparing to offer mail support for Chinese consumers. QQ, 163.com and 126.com already offer preset mail account information.
Recent rumours suggest that the company is planning to launch a cheaper iPhone 4GS in order to target the growing Chinese market.
Apple could provide the Chinese market with even more iOS products should it manage to close a deal with China Mobile, which appears possibly to be in the pipeline.
