Hi I've recently changed from an HTC Desire to a GS2 and I have a few queries. I've tried searching online for a solution to them, but so far have been unable to get a definitive answer. My queries are as follows: 1. On my Desire, I just dragged and dropped music files from my itunes folder and they worked perfectly with the built in music app. With the GS2 when I've tried to do this I am unable to get any artist information. I downloaded the playerpro app and this hasn't made a difference. Is there anything I can do to rectify this ie an app that can read this missing tag information, or do I just have to put up with it? I don't want to convert all my files to mp3 format. 2. I read on a forum that the GS2 is a 4g device, and the sim needs to be set up for this. I am still using the sim I had for my Desire as my contract has another year left on it (Vodafone), and I just bought the GS2 and stuck my sim in it. I've not experienced any problems yet, but do I need to get Vodafone to upgrade my sim in order to get the full benefits of the GS2? Any help in answering these queries would be greatly appreciated.
