Decent Low Budget Smart Phone?

[Niall]

Piggy you couldn't be more wrong!

Tom, have you ever had a play with an iPhone? I think one would suit your needs. They tend to be more reliable than android, less laggy and more stable.

If you're set on having new, the Nokia as Chris said is a safe bet. As I mentioned, Amber is even considering one now over her iPhone 5S!

Id agree here not so much on the more reliable part though. I think a iPhone would suit Tom due to the simplicity of them but if he's adamant on buying new, he won't get any iPhone for his budget.
I would seriously consider second hand Tom. You'll get a lot more for your money.
