heya guys. i have a question , why can`t i use ANY (that i could find) app for my phone (a samsung i5500 -galaxy 550 - ) that receives gps signal , without beeing logged in a wi-fi network , or 3g from my provider. i thought that the gps signal is free , and the phone having one receiver, i could use it for free. and another question , i went mad on downloading apps for my phone ( first time smartphone user ) at some point the internal mem got full , but i have a sd 1gb card in it , how could i set the phone to use the sd card as a default storage and instaling space ? thnx a bunch , and sry for the grammar.
