how can nokia compete with the iphone? its a hand held computer that has everything you could ever want. i dont have either but if i was gonna spend a lot on a phone or get a new contract it would have to be an iphone
The gayPhone is not for everyone 
They are trash, for kids and people that dont mind 500mb's internet allowence for £35 a month.
Every Iphone 4 user that I know of on O2 is so scared to use his 3g because of costs. They just want to hook up to WiFi.
My iphone 4 on 3 lasted about a week, I decided that I did actually want to view internet pages that used flash so I sent it back. DPD came out to collect it and dropped me off a BB Torch.
I have never had a BB before but I am smitten with this one! 
Horses for courses. No phone is perfect for everyone, you just have to find something that suits your own personal needs

That said, I'm surprised a Gooseberry suits anyone's needs outside of corporate environments :-/ (Rasberrys are really good for centralised management - thats their niche, but at the expense of functionality/usability).
As to 3g usage, thats a fear put about by people who tether their phones (legally or otherwise). Mrs TB's contract O2 is 'unlimited' (soft capped at 3g when investigating). In the (almost) year and a half since she's had it, I don't think she has done 1Gb download (and about half again for upload). She uses it a lot, and uses Exchange push for mail.
My O2 is 'unlimited' data on PAYG (first year is free unlimited data), not found what the 'unlimited' soft cap is. I'm quite a heavy user of data, yet I too have only managed 1Gb download in the (almost) year I've had this. Once the year or unlimited free data is up, I'll be popping it onto contract, £15 a month, with a 500Mb limit (O2) or £15 a month with a 1Gb limit (Tesco, which uses O2) - (I'll probably go for former). I probably abuse mine as well, as I tend to stream TV (live and recorded) from my Media Center at home

However, the cap is irrelevent, all smartphone contracts have a 500Mb-1Gb cap (stated or soft capped), as the mobile providers haven't kept their infrastructure in line with potential use (in same way broadband providers never foresaw the P2P/Usenet issue flooding networks).
I know of nobody with a contracted data allowance switch off mobile data.
