The iPhone 3G goes on sale tomorrow at all O2, Carphone Warehouse and Apple stores. Most stores will be open at 8am or 9am depending on which store it is, and we've been reminded that all stores only have a few dozen handsets in stock. There is a limit of 1 iPhone per customer, or 2 per business customer.

I'll be at the local Carphone Warehouse eager to upgrade my existing iPhone to the new 3G one tomorrow early morning. I will give an update to whats new once I have my hands on it.

UPDATE:

After recieving the last iPhone at my local Carphone Warehouse and upgrading and therefore signing up to another glorious 18 months with O2, I have my iPhone 3G in front of me. The audio jack is now flush so theres no need for those expensive Belkin adapters (or cutting your headphone wire, as a friend did to save seven quid). The back is black and glossy and more pebble like, the buttons on the side are silvery chrome. The 3G seems slightly longer, and is definately a lot sexier.

I downloaded the Myspace app and the Facebook app, which both work well. Facebook have a function so that their new "Chat" service can be utilised by iPhone users, which is cool.

The speaker seems to be the same (rubbish) one, which is a shame because a decent speaker on an 8GB music player would be nice :(

Contact searching is great, no longer do I have to scroll through my contacts to find someone. I wonder how well the new iPhone will work with my car stereo, and whether it will actually sync my contacts with the head-unit.

Activation was easy, the only problem I had was downloading iTunes 7.7 (first it wasn't available from iTunes and then my connection was too slow) but after that it was all plain sailing, except for when iTunes asked me for my iPhone number and wanted a 3 digit area code with it... anyway...

All in all, the new iPhone looks, feels and plays much better than the old one. So what are you waiting for? Go and get one! (actually, I don't think you can get hold of them until Monday if they're already sold out where you are).
