UK 3G may come close to breaking point this Christmas

There has been recent news that the UK's 3G networks may be close to breaking point to the overwhelming demand of phones that use 3G. The main phone that was mentioned was the iPhone. I know the iPhone is one of the main phones that uses 3G, but you can't go blaming one phone as the main culpret. I know there are many other phones out there that use 3G like the HTC phones and the Blackberry phones. I always thought that different mobile providers have different networks and I know that there are many mobile providers in the UK that will be releasing the iPhone after the new year and other 3G phones.

If anyone knows anymore or has a different opinion, post a comment.
