i've been having issues with my mobile me and becuase of that have started using gpush until i get mobile me sorted out. this got me to thinking, how long are apps like gpush going to be around? is it possible that one day the developer just decides he doesnt want to run the servers that make the app work and just shut down? is there any kind of contract with apple where they have to keep the app supported for x number of years, months or whatever? just something that got me thinking.
