Transfer My Data is a handy utility app to transfer contacts over Bluetooth from your old phone to your new Nokia Windows Phone. The Nokia app was updated to version 4.1 update and with no change log, the changes aren't as obvious. We are seeing that SMS and Photos can be transferred as well as contacts from supported phones.
Storage Check gets bumped to version 1.1 and adds landscape view and the ability to manage your downloaded maps. You can still clear the temporary files to free up some storage space and view details on the apps/games install on your Windows Phone. It basically puts the features of the Beta version of Storage Check into play for the firmware version.
The Storage Check app can be accessed from you Nokia Lumia Windows Phone setting on those phones who have received the 1308 firmware update. For those who haven't received the update, you can find the Beta version of Storage Check here in the Nokia Collection.
Transfer My Data is available here in the Nokia Collection for both Windows Phone 8 and 7.x devices.
