I have a computer, it's an HP Pavilion, and it doesn't have Bluetooth. I am a musician so I need something to use, and the chord to my mini bluetooth speaker doesn't work anymore. Could I use my Jailbroken iPhone to somehow connect to the computer, and play the PC output through the iphone to the speaker? Thank you.
Can I connect my bluetooth speaker to my computer via jailbroken iPhone?
I don't believe so. You don't have bluetooth, so you will need to plug the iPhone into the computer. Copy the files you want to your iPhone. If you have an iPhone, I believe you have enough money to buy temporary wired speakers.
You can go with speakers:
Plus there's also a headset output ON The speakers, if you want them:
These are not really good quality, just cheap for temporary till you want something more advanced.
