Is it good value to buy an iPhone 4 for £170?

Has been owned by a friend for 4 months but she's upgrading to the iphone 5. I'm not sure if 170 is a rip off or not? Opinions please! Should i go for it or not?

That is probably the best deal out there especially for a 4 month old iPhone 4 they are about £400 new so £170 for just four months is brilliant. BUT make sure everything works. Or else its you'll be stuck with a rubbish phone in the end and paying £170 also check for cosmetic damages!

Amazon are selling a used iPhone for £200 so £170 is not bad.

Very good, usually go on ebay for around 220-250 pounds

Not sure it is worth even 170 these days

it will get no more (useful) updates
Yes, it will update to iOS6, but its not getting the nice features
they are only on the 4S and 5
So a 4S, great, a 4?

upto you,
it is a cheap way to get an iPhone
but as it clearly being phased out by apple, you have to ask how much longer it will be usefu

You also need a iPhone plan to go with it
170 for a 24 months = 7 pounds/month
and t-mobile already gives a Free iPhone 4 on the same plan as SIM only (26/month)
so ask youself how much to pay for a SIM only plan?
if it is more than 19 pounds - you lose (19 + 7 = 26)
