Despite poor start, Apple iPhone SE is becoming hard to find
On Apple's website, the 16GB Apple iPhone SE ($399) is easier to find than the 64GB model ($499). For example, a 16GB iPhone SE in rose gold ordered from Apple for use on Verizon, AT&T, T-Mobile or SIM-free, will arrive April 12th. The 64GB variant will land at your door between April 20th and April 27th. The actual date will depend on the shipping method used. The same scenario is playing out internationally, especially in emerging markets where Apple is targeting sales of the smaller, more affordable iPhone SE.
Demand was said to be steady last weekend for the 9.7-inch Apple iPad Pro; the tablet went on sale March 31st, the same day as the iPhone SE. Currently, same day pick up of orders for the Wi-Fi only version of the slate from the closest Apple Store is still possible. Orders placed before 5pm can be shipped the same day and received the very next day.
Apple's shipping dates would seem to be the best indication we have of demand for the new devices, and these figures would seem to show that demand for the iPhone SE has picked up strongly during the week.
