I would highly recommend the BlackBerry Curve 8900, it's an amazing phone. You can text, ring (obv), email, facebook, yahoo, flickr, msn, etc etc, and also you can surf the internet really easily because of its tracker ball and qwerty keyboard. The amazing thing about it for me is that it makes receiving emails and facebook message just like receiving a text, and you can link up several accounts so that you don't have to laboriously check all your accounts everyday. Also it has BlackBerry Messenger (BBM) which is instant messaging for phones which is very handy if you have friends that have BlackBerrys, its £5 a month for this extra service but there is no limit so it is effectively like a free form of texting, you can send pictures etc through BBM aswell. At the moment I am on Flext35 contract on T Mobile, so I pay £35 a month (18 month contract) and that gives me £180 worth of credit to spend on texts and phone calls but I also get unlimited web'N'walk (so unlimited internet) and then I pay £5 for the BBM and other BB services, I think it's quite a good deal but if you look about the T Mobile and 02 sit you will probably be able to find a cheaper deal. I would rank this BB as the best phone I've ever had.
Got one of these for work and they are incredibly practical too, although I do find the keyboard (using symbols etc) very clumsy compared with ordinary predictive text phones or the N97 for that matter
fat fingers?
