from wifi back to 3G network issues in browser
 

i turn on the wifi when i get to class and go to hotspot log in to use the browser in wifi mode... when i turn the wifi off it tells me that i need to reconnect the phone to the wifi to use the browser. in options i try to change it back to internet browser from hotspot browser but it wont let me. the only way to then go back to 3G is by shutting it down and even that dosent always work...

am i missing something here?
