Christmas is fast approaching, but if you haven't gotten all your holiday shopping done yet, take heart -- there's still time to order and receive a new phone by the 25th with at least a few major online retailers.
These deadlines are for guaranteed delivery by Christmas and assume that items are in-stock and shipping to physical addresses within the contiguous United States. Be aware that new activations occasionally incur delays from carriers, so stay on the safe side and don't wait until the last minute. (This is not a comprehensive list, so feel free to add to this if you see anything missing.)
