You might finally not have to use some tricks (that might or might not work) to add words to iPhone’s dictionary and get an easier way to teach your iPhone to swear in iPhone OS 4.0.
Gizmodo has just reported that they have discovered a screen in the iPhone OS 4 Beta 4 released yesterday, which suggests that it will get a custom dictionary.
You might have noticed that your iPhone doesn't know the swear words. So every time you try to use one, its auto-correct feature kicks in and gives you some weird alternatives.
It is times like these that you really miss the ability to add a word to iPhone's dictionary.

If or when Verizon Wireless offers the iPhone it could support simultaneous voice and data using VoRA, according to BGR.
One of our Verizon guys hit us up with some pretty interesting news. We have been told that when the mythical Verizon iPhone materializes, assuming it’s not a LTE unit, it might launch with VoRA; Voice over Rev. A. According to our source, Verizon has been testing VoRA as a precursor to VoLTE, and as long as the network upgrade timeline and iPhone release are aligned, we should see this happen. If it happens.
