I am new to android (never owned one before), and will be getting my first android device soon. I have one gmail account, another mail account with google apps and a yahoo mail account, so my contacts are spread around. So I made a separate gmail account just so that I could fetch all contacts at one place and delete the ones I dont need, and then do selective contact sync with android device. I will also use this account to back up my SMS's and any other kind of data that can be backed up in cloud. I wanted to ask you guys when setting up the device, should I use my newly created gmail account as primary account or the one that I am using on daily basis?? My main concern is that once I bought apps with one account, I wont be able to use another account again later, so I want to get it right from the start. Also, can android still use calender and email from my other gmail accounts as primary calender/email??
