Mobile Phones

i've got one of the most basic nokia's out there. i went through a stage of losing my phone on the farm somewhere on a regular basis so bought the cheapest i could find. have has it for nearly 3 years now and it is crashing on a regular basis and sometimes wont turn on for hours, so i guess it's time to get a new one.... have been putting it off....

so i think i want a phone with internet and email capabilities, but have no idea which one. i have seen so many iphones with damaged screens, i think i'd break one within days.... so what do i go for? i have absolutely no idea.... please help. pretty please.

also need to change from orange (rubbish signal in my house) so who is better, o2 or vodaphone?

Please don't go for Vodafone, I'm on an 18 contract with them, and dying to get out already, just expensive, expensive, expensive. Total rip off compared to Tmobile my old provider.
I'd say o2.
