IOS 5 Beta 2 without developers account HELP?

So not too long ago, iOS 5 Beta 2 was released, but I am having second thoughts. 1/10 websites say that updating your iPhone to iOS Beta 2 using the by-pass (For non developers, you know that tripple home click and emergency call thing ) will remove carrier connection, which means that your iPhone cant call people or use the internet. Is this true?
