An email was sent out today to all Vodafone customers about the release of the iPhone on their network today. Vodafone has 
joined the other 3 carriers of the iPhone in the UK (O2, Orange and Tesco Mobile.)
According to Vodafone, they estimate they will be able to sell 50,000 iPhones by the end of the day. If they achieve this they will beat Orange’s launch record of 30,000 and outsell the Google Nexus One, which only sold 20,000 in it’s first week.
