Hi, looking for some advice on new phone, my contract is just about up on my MDA Vario, looking for the next best thing on the market just now, like the idea of having a mini pc in my pocket, not bothered about camera, just looking for the best pocket pc spec with reliability, sat nav would be an advantage as well as would built in WIFI, help on choice much appreciated, would like to stay with TMobile web & walk service which is roughly £40 a month, so I don't want to go over that amount if possible, or maybe I would consider another network that offers unlimited web access.
