Microsoft is currently preparing an update for Windows Phone 8, codenamed Apollo Plus according to sources. The new OS update will bring new features to Windows Phone 8 that weren’t ready for its initial release.

These features, which will be pushed to devices over the air, contain VPN support, audio improvements, and a Wi-Fi connection fix to enable an “always-on” connection. In addition, sources have also confirmed it will be fixing Bluetooth issues being experienced by some users.

As far as a Notification Center and other features users have been vocalizing since the new OS’s inception, Microsoft said it “ran out of time” on this feature but is said to have plans to implement it at a later date. Other features will be announced by Microsoft at Mobile World Congress in February.
