Any question answered...

Whats a good cheapish 2nd hand smartphone? My girlfriend wants something to do her emails on and her new tariff has unlimited web stuff so a smartphone seems the right option. I only know about iphones - and all I know about them is they're expensive!

£100 brand new, does everything an iPhone does (except attract hordes of fanboys), has a touchscreen and the o2 simplicity data plan is quite good
Although, battery life isnt great if you leave your data roaming, gprs, wifi and bluetooth on all the time,
which most people seem to do unknowingly.
