title: Location aware mobile app, need advice on which technologies I should use
body: <p>I'm making a server side website for mobile devices. What I want to do is have a member system that users log into. After logging in their geolocation is sent to my database, which returns a list of destinations in the area (restaurants, stores etc.) This has been done I know, but I want the locations in the database to be user generated, they can submit their geolocation to the database and saved.</p>
  
  <p>I know Flex, Actionscript, HTML, learning php/MySql. I'm confused by all the mapping options out there and what I need to use and don't need to use.</p>
  
  <p>Hoping someone can help me figure out what I need to do/use to accomplish my goal. Thanks in advance.</p>
