Iv been using this for a few days now on my 3GS & my battery life is terrible has anyone else had any problems?

Nope, battery fine and better than before

the problem i have is when you press the home button sometimes it dosent do anything you have to press it again,

but this might be me as i find i have to press it a bit harder than before ??

also i cant for the life of me get air print to work lol

Do you have the new beta version of itunes with airtunes?

i have 10.1 beta

I have iTunes 10.1 and as yet no update for my iPhone 4, how long will it be till I can upgrade it?

Only got my iPhone today

It'll be another week or two, apparently. iOS 4.2 has been delayed due to a WiFi connectivity bug with the iPad.

Okay, thanks for that, I'm a new iPhone user, and its all foreign to me! I have previously used iTunes though as I have had a shuffle and iPod nano in the past!

I was reading they removed AirPrint from the latest build due to some stability issues. But there are hacks out there that can re-enable it apparently.

AirPrint is still present in 4.2 and it works fine if you have a printer that supports the feature directly (which is currently only about 5 models of HP printer).

Apple removed support for AirPrint from Mac OS X 10.6.5 and iTunes 10.1 for Windows. That means that you can't use iOS 4.2 to print to a printer that is shared through your computer. As you have noted, it is possible to enable it by using some files from the beta of iTunes 10.1

do you have any info on how to do this ?
