Apple will be showing a preview of iPhone OS 4 on April 8th this was reported by Mashable earlier you can read more about this over at Mashable. Now that you know that, I want to share a quick story. I was syncing my iPod and saw that the next time it was going to look for updates is going to be on 4/8/2010 the same day Apple is going to show off iPhone OS 4. I e-mail Apple asking about this but as of right I have not herd anything back just yet. What I think will happen is there will be a minor update that day. Not iPhone OS 4. I took a screen shot of what my iTunes said so you can see. If there is any updates I will keep you all posted.
