I did a lot of research for this.. I didnt think it was worth the extra fiver a month for 200 extra minutes tues to sat!.. unless your on the phone for 4 hours a night/day I dont think you will even hit the 600 a month.. dont forget you have the free weekend calls upto maximum of 2000 mins.. your just paying the £90 a month in monthly installs
buying the phone outright seemed the better option to me
features are brill.. it has everything! I believe interwebing and watching vids all day will drain any phone of its battery life.. thats the only downside i hear… but who spends all day watching videos on there mobile? i just listen to music and do the odd browsing in bed if i cant be arsed getting up at night *using my wireless network of course*
