Apple has now released iPhone OS 3.0 beta 4 along with iTunes 8.2 pre-release according to a post over at engadget mobile, and this is just two weeks after the last revision went live.
They have played with iPhone OS 3.0 beta 4 and checked on the previously empty “Store” pane and guess what, now it’s populated but they also say it’s somewhat boring because all it does is allow signing into your iTunes account and on doing so there is a button to take u to a web page whereby u can alter your credit card info.
As for iTunes 8.2, they say they were warned that the application would verify their Apple iPhone was activated for using beta firmware along with some legal stuff.
