Just arrived today, second hand, as new on Ebay for £18.
Not a smartphone, but Dual SIM and a battery life, that my friend confirms can do 5-6 days easily.
With two stag do trips coming up, and a few long weddings to attend, I wanted a back up phone, that I can still access WIFI from, have option of Music, a basic 3MP Camera and a long battery life. For the money, can't complain.
I'll upload a small review shortly, with my findings.
* Sticker on the box, says now available with Whats App, which is pretty cool.
