When I try and call someone and the line is busy, my phone says "Call Cancelled" - instead of giving me a busy signal. It's been acting strangely lately. Just a few days ago "ear" part of the speaker didn't work, but the speakerphone would work. At the same time, the iPod part wouldn't play through the speaker. I restarted, and it didn't do anything. Then, the next morning, it was all fine. I have a 4GB, and I'm hoping to put things off till they don't have anymore and they're forced to exchange my for an 8GB (I know, greedy, but only a little bit greedy ) Anyone else have similar issues?
