so my iphone4 that i purchased on Feb 14th had some hardware issues over the last week or so and i had apple send me a new phone. They told me that they would put a request in to send me a brand new phone. The one they sent me looks new but i still cannot tell if its new or refurbished. If it was refurbished should i be concerned about a used phone? i feel like hardware issues after owing the phone for a month and a half i should get a brand new phone. It still could be a new phone they sent me but i really can't tell. I dont want a problem to go wrong with a used phone because this was an expensive phone to purchase. Any thoughts about what i should do about this? should i just set this phone up not knowing exactly if it is new or refurbished? has anyone experienced this before? thanks!
