Hi guys

Is iOS 4.2.1 the latest upgrade? I've only just got the phone sent to me from Vodafone as I was having major issues with a HTC Wildfire so they swapped it for me.

I have a slight issue with it... whenever i make or recieve a call the speaker for your ear (as opposed to the speakerphone kind) is really tinny / muffled / crap. Is this just an issue with this model or a possible fault with the handset? Would upgrading the software help in anyway?

Cheers
