Has anyone applied to drive with Amazon.com in their Flex program? I just received my first email inviting me to attend a 2-hour webinar and complete the online form for a background check. The only catch is that drivers need an Android phone to move forward in the process, as Amazon doesn't yet support iOS. I'm interested in knowing if there are other drivers who are considering this as an alternative or additional option. Is it worth the time and effort to get more details?
