Some developers were able to find more details of next iPhone from gettin deep into the beta firmware 3.0 which was release last week.

These developer got traces of next version iPhone being capable of higher wifi speeds by adding 802.11n support.

Also, they found that Apple could add video recording and uploading the video right from device with some reasonable editing on iPhone itself!

This could be true and we can expect lot more, and all could be real during this June WWDC 09 event.
