Nokia and MS do something and Release Amber update to L520 as soon as possible... I heard that if i am out of space i cant even download amber update which requires 1.5Gb space.... :unhappysweat::crying:
A TIP- When you receive the Amber update notification, just do a reset(to clear all the memory), update the phone and then reinstall all the apps. Reinstalling apps will be easy, can be sent through push notifications from your WP account online but you will have to enable "Find my phone" setting.
