Bear with me this is kinda my first write up/how to. I will try to answer and add on questions/solutions as they come in... If you have a better solution please post it here and lets get a working solution for the community!
So first I got a spotify free account which allows you to stream music to your computer for free. The last two days I was researching and downloading apps that remote connect to my computer and stream audio over 3G. Now I know there are apps that let you stream audio over wifi but what good does that do when your out and about or driving around and want to listen to music. I came across Splashtop remote ( http://www.splashtop.com/remote
) which seems to work for me. So here goes...
1-Get a Spotify account
2-Get splashtop remote for your iphone and the computer you have spotify on.
3-Connect iphone to comuter through splashtop remote and you have full access to your free spotify account and your whole computer with audio!
BTW the comp I'm streaming from is windows xp and iphone 4 with 4.3.1 havent really tested anything other than that out let me know how it works for you. Only downside to splashtop remote is I dont think the app multitasks so if you back out of the app you will have to restablish connection so its not a 100% workaround solution but perfect if you really want to hear a certain song on the spot.
There was a few settings I had to mess around with on the computer end.. In the splashtop streamer on the pc go to the settings tab an make sure the box is checked for the redirect sound and mute computer. I also had to play around with the drop down menu below that regarding the remote client playing the same sound from the PC to (My Speaker name) Audio-Stereo Mix.
I dont know if you will have the same options as I did so please post here if you have any problems or questions.
If anyone comes up with a better solution please let everyone know!
And a lil thanks if it worked for you
