Q. I bought an iPhone in New York. Someone told me I can't use it in the UK. I'm being told that I can't use it with Vodaphone (the French can, why can't I?).
A. You'll have to hack it to run it on a network other than O2. Look for JailBreak. If you can going the web with the iPhone go to Jailbreakme.com. There is a program there which will unlock the phone for you.

Q. I just bought Leopard, do you need to do the back up yourself?
A. Yes - always, always backup before installing and operating system.

Q. I have a G5 and G4, I can put them next to each other, I get a WIFI signal with the G4 and the G5 is intermittent. Why? It is connected to a wireless router.
A. There may be some interference affecting one of the machines. Either external (microwaves, fridges), or maybe from the materials the Mac is made from. Log into the router and try changing the Channel number to 1, 6, 13 (avoid 11).

Q. We've heard about the first Trojan. Is this the end of innocence for the Mac, is there more to come.
A. It can only get worse. Even as a Mac User, you still need to be aware of exploits, trojans and dodgy websites. Avoid following links to websites, try to make sure you can see the full URL. Alternatively use the openDNS.com anti-phishing service.

Q. How do you operate email or the web browser.
A. All configured automatically when you plug it in.

Q. I've been dragging photos onto the Photoshop Elements 2 icon to edit photos. Recently it says: an error has occurred when trying to download a files from Adobe online...bad request etc. I've been told the re-install it, which I've done 4 times, but I get the same message. The message freezes the program, requiring a force quit to exit. Help.

A. ?

Q. Any replacement for Eudora for Leopard?
