We're sorry for any confusion this has caused. To clear this up, we can confirm Vodafone has approved the 2.2 update and we are awaiting confirmation of the availability from Samsung. As soon as we can verify ourselves it is available we will update you.
However, in the interests of avoiding any further confusion, we have now removed the original info and will re-post it when the update becomes available.
Occasionally, some manufacturers will release the update before informing us of its availability. Should any forum member be able to verify its availability before we do we would greatly appreciate it if you could inform us.
