I can't get Wifi on my iphone 3g - but I can't back the phone up

Ok, this sounds like a problem that only a complete numpty would have (hands up, that's me).
Here is my issue: I have an old iphone 3G that a friend gave to me - (primarily to use for Wifi as I don't have a computer and I needed to access the internet). For a while (a week) it worked FINE and then all of a sudden my phone will NOT connect to any wifi network. It just brings up a message that says 'cannot connect to this network'.
I have turned the airplane mode on and off
I have restored network settings (several times)
I have turned the divice on and off
and I have checked for new software updates on my friends computer - but apparently we're all good there *(even though the muppet in the apple store was like ' oh, you've got old software we're up to 5 now just update it - given that she couldn't find itunes on an ipad, I'm inclined to think she knows not much more than me).
I know the natural thing would be to reset the phone but I DONT want to lose all my contacts / photos / messages etc.
I don't want to Sync the phone to my friends computer cos it would mess up all her contacts etc. as she syncs her phone to her computer.
I'm a bit stuck.
HELP!?

An iPhone 3G can only be updated to iOS 4.2.1...that's the end of the line for that model iPhone. If that's the iOS already on your phone, there are no further updates available.
