i have been on vodafone for 4 years now, and i have had the nokia E71 phone for a year now, and within the past few months i have noticed i dont get much reception, my reception is always up and down and sometimes i have none and withing a plit second i will have full, when people ring me sometimes it just cuts out because my reception runs out even though im in my own house which isnt rural or anything, i want to get the iphone for christmas but not if it means keeping the reception i have now because its shocking! why is this happening ? i heard vodafone joined up with 3 ??
