i have my Nokia E71,Touch Pro ,and iphone 3G 8gig ,but so far i just succeed trying my GPS on iphone,the rest,i dont even know how to use them at all,Nokia seems to speculate softwares,intended to enhance it,but infact they're troubling their users.Htc touch pro still can be learnt,but it takes time,as am not travelling too much,so i dont think of exploring the GPS applictions in my pro,but E71 ,the most common phone with me of all time,this phone is very complicated,kinda break my head to find a way out,till now i have no way to use them tho.what a useless Mapking,they charged me.but no Maps out.
