Ah. I thought it was named after WhatsApp and was trying to ride on the tails of success. I wonder if more than just me would think that? I think it would make make sense without the &quot;S&quot;. Just &quot;WhatCarrier&quot;.<p>Either way, I like the idea but I am not going to download it. I have really limited space on my phone and while this is a useful app, it&#x27;s not that important to me. It would be a really cool feature if it was built into the phone&#x27;s OS or launcher.<p>How do you figure out the contacts carrier?
