Might it be that 3 tends to be worst for signal strength because its mostly/all 3G whereas to get decent coverage/signal you often have to drop back to 2G on other networks. I use 2G on my phones because the signal will almost always be stronger (don't you need less base stations for GSM on 900MHz) and the battery life will be better.
Also isn't there some network sharing between 3 and Orange/T-Mobile - it's something to do with the new company created (Everything Everywhere). I could be wrong about 3 using this though.
As for the friends phone, try the SIM in another handset to see what signal strength it gets in the places the other phone is poor. It will show if it's really the network or a crap phone.
