I just got my husband a phone through the TAB but he told me now he doesn't want the one I got him but something else can I take it and switch it? It hasn't been used yet. He wants to go from the iphone to an android.
How long have you had the phone? If it's still within 14 days you can return it but if it's over 14 days the phone is yours and my best advice would be to sell it and use whatever you get towards the new phone.
