Im just finishing my 12 month contract with 3, ill be going back to orange and ill tell you why... Since the moment i opened the box the phone came in its been non stop dissapointment and hassle. The reception is the worst ive ever had (ive been on all the main providers, and i live in mnachester - hardly out in the sticks) mine has no signal when everyone else has full, it drops calls all the time, sometimes it decides it wont even ring out when its showing full strength. people say they cant get through to me, although that works in my favour sometimes
As for the browsing, its still 3's "walled garden" affair i.e. not much use although they are adding some more sites as they go (i can now get ebay and gmail lite - dont work very quickly tho) having said that the music video downloads are a good feature... if your phone has the memory to store them. I got the motorola a1000, without a doubt the worst piece of junk i have ever had the misfortune to use... awful.
In short, i would sooner eat my own **** that get another three contract
P.s. the customer service issues are a pain too, all guys in pakistan with limited english, however a nice english chap called me up to make sure ill be extending my contract... when i started to explain i wouldnt because of poor phone quality etc... the network dropped the call!
