At this point the Sidekick data outage needs no introduction. T-Mobile USA now reports that Sidekick data syncing is back online but it is still “unstable”. Users should back up (use tutorial here) any data and restrain from performing a hard reset. Simply power-cycling your device (Menu ->Power Off, letting your Sidekick turn off on its own and then powering it back up. DO NOT do a hard reset as your data will be lost) will enable your data to start syncing with the Danger/Microsoft Servers.
Microsoft/Danger have now made the necessary fixes to their network to restore the ability to sync your data. This means that your contacts, calendar entries, to-do lists, tasks, etc. will now sync on the network, just like they did prior to this data disruption. However, you must power cycle your device following the steps below in order to begin the syncing process.
Well there you have it! Don’t forget to leave your thoughts in the comments!
