Buying an iphone for someone in another country.

1. You can buy one in the U.S, but warranty will only be available in the US. So if anything happens to it, it will need to be physically returned to the U.S. for warranty service.
2. You won't ben able to ship it to Nigeria directly form Apple. That is, you will need to ship to a U.S. address, and then send it to Nigeria yourself, at which point, if something happens, our it gets lost in transit, it will be your responsibility and Apple will not help you.
3. Make sure you select the no carrier option, so she can use a carrier in Nigeria. Don't buy it form places like Walmart or Target as they will be locked to U.S carriers.

There are a lot of unknowns regarding Apple's warranty and even out of warranty service. Apple's terms say that iPhone repair may be restricted to the country of original purchase, although much of that has to do with regulatory issues. If you're comfortable enough with that, then by all mean there's nothing wrong with buying an iPhone in the United States as a gift for someone overseas.

Thank you so much. This helps put me at ease a lot. I was really dreading paying double for a phone. I'm assuming unlocked and the no carrier option are the same thing?

In general, yes.

In the U.S Apple Online store its the "Connect on your own later" option.
