title: iPhone 3G / WiFi Connection
body: <p>I like to make an application for iPhone where it uses a Wifi to collect some data and use 3G to send this data to internet. The Wifi connection would be adhoc and wouldn't offer any internet connectivity. So, in this case, wifi would be just a data collection interface. </p>
  
  <p>Is this possible? </p>
  
  <p>More technically:
  - iPhone connects to an adhoc network and picks an auto IP such as 169.254.x.x
  - Fetches the data from 169.254.1.1 (known ip of the sensor)
  - sends the data using web services to www.xyz.com/dataEntry</p>
  
  <p>Also, I make this small test:
  - Make a P2P Access point on my Win7
  - attach my iPhone to the P2P access point
  - try to browse a web site on the internet and this fails. I cannot open google.com for eg. </p>
  
  <p>How about Android, albeit less important I would like to offer this app on Android too..</p>
  
  <p>Thx,
  F. </p>
