Vodaphone is the latest of the UK’s major phone networks to offer the iPhone to customers.

The cheapest tariff available is £30 a month for 24 months, plus additional handset charges ranging from £59 (iPhone 3G 8GB) to £239 (3GS 32GB).

Both business and consumer contracts are subject to a 1GB monthly data limit on mobile internet use. Orange has a decent limit of 750MB per month.

Vodafone and O2 both offer unlimited wifi use. Orange’s data limit includes connections to the internet via BT Open-Zone wifi.

Both O2′s and Orange’s lowest tariffs – £34.26 and £29.36 respectively – are on a 24-month contract and come with a free iPhone.

Vodafone comes close with a £35 a month contract over a two year period, also including a free 3G 8GB handset.

Tesco Mobile tariffs start at £20 a month for 12 months – with a £222 charge for the same model of handset. However, Tesco says that the shorter contract will enable customers to upgrade more quickly.
