You can transfer your contacts from your Instinct to your Epic using bluetooth.
Or if your Instinct is still activated;
Go to your "Sprint Mobile Sync"(Contacts) page(from your account page at sprint.com) and "Export" your contacts to your PC in .csv format. Once you deactivate your Instinct you lose access to the Mobile Sync page alltogether and won't be able to get to your contacts. ...Take the .csv file and "Import" it to your Google account and you will be ready to sync it to your Epic/EVO or most of Sprint's new smartphones.
