New Phone

Any modern phone that has a touchscreen of at least 4.5" should be fine.

Betfair mobile is rubbish anyway, so you'll have to use an alternate Betfair-type app....I use Traderline as it seems to be the best of a bad bunch.

Hove, when you go to edit a bet, say that's not been fully matched, you hit the my bets tab and takes you to the bet, does that screen page freeze for you by any chance which means you cannot edit, submit or even go back to the original page? it has done to me in the past.
