Top 10 articles: Facebook pros and cons, and IPv4 warnings

The big hit with V3.co.uk readers this week was our run down of the top 10 best and worst things about Facebook, one of which has to be the fact that it was 'easy' for a hacker to expose details on 100 million Facebook accounts.

This was followed by the news that IPv4 addresses will run out in under a year, Apple's rollout of the iPhone 4 to a further 17 countries, and HMV's aggressive move into the digital download market.

News from the Black Hat conference was also popular, particularly an ATM hack and the introduction of DNS Security Extensions.

Meanwhile, T-Mobile and Vodafone have started promoting Nokia's N8 smartphone, and Apple's share of the smartphone market has dipped slightly.
