iOS 7 beta 4

Just in case you didn't know, iOS 7 beta 4 has been released today and ready for download to all devs. There are a few changes that you may notice immediately. It feels a little less laggy. At least to me. Also the lock screen is a little different. For some reason my lockscreen wallpaper shifts to the left and right a little bit, nothing that annoys me but just pointing it out. Also when getting a call the remind me later or text the person thats calling you fonts are smaller and more opaque instead of it being so heavy. I honestly just downloaded it about 15 minutes ago and those are the the noticeable things at least to me. I will post if there is something worth posting for. Thanks
