Hey everyone, I have an iPhone 3GS 32 gb that I got about 3 days ago. I have a fm transmitter that charges the phone while transmitting the music through the radio I was wondering if this continual charging through the transmitter is bad for the phones battery? Should I invest in a transmitter that doesn't continually charge the phone? Or does the phone stop recieving charge once it gets to 100 and shows the charged indicator? Thanks for any replies.
