i just wanted to let people know that since i got my iPhone 6s+ in September , Verizon and sprint kept telling me that my device was not compatible. the last i heard from sprint was on October 26h and they told me that my iPhone was not a sprint device. the iPhone i have is the T-mobile unlocked iPhone 6s+ (a1687) that works on Tmobile , Verizon and sprint. im not saying if this policy actuality stopped you from activating a new line of service but i just wanted to say that sometime in the last week Verizon and sprint now whitelisted my MEID and nothing is stopping me from switching if i wanted to. they both pretty much told me its a compatible device the same week. for about 69 days those two carriers were trying to tell me i could not activate this iPhone because it did not belong to them, and now i guess everything is okay. i guess there was a 60 day waiting period after apple released these phones and verizon and sprint okayed them.
