Apparently O2 customers are somewhat disgruntled with having to pay for the remaining time on their O2 iPhone contract if they wish to upgrade to the new iPhone 3G S handset, and pay full price for the handset as well reports telegraph.co.uk.
The word is customers have been flooding internet forums and Twitter with said complaints due to many expecting a similar deal to that of the iPhone 3G back in last July.
O2 has confirmed however that customers will need to buy out their current contract before switching to the new iPhone 3G S, which has O2 iPhone customer furious.
