"I've been happy with my progress, but there's a long way to go," Jones told a news conference on Thursday.

"Halfway through last season I decided to do things my way instead of in textbook fashion.

"My decision was made after the culmination of a few matches in which I wasn't happy with the way I was catching the ball, so I went back and thought about the times when I was happy with it.

"You could say I followed my instincts, although I suppose my style is a combination of several different styles."

Jones said he spoke to former England wicketkeeper Jack Russell, who advised him to be relaxed but mentally aggressive, wanting the ball and wanting to be part of the game all the time.

"I needed to tune up on that, because as the wicketkeeper I've got to run the fielding show out there."

Jones showed his batting prowess in the second one-day international against Zimbabwe on Wednesday when smashed 66 off 46 balls to help England recover from 121 for five to total 263 for six.

Jones shared a record sixth-wicket stand of 120 with Kevin Pietersen, who scored an unbeaten 77.

"We could have been bowled out cheaply, and that would have been embarrassing," Jones said.

"But it set up a situation for me to go out and show I could score runs in a one-day situation. It was nice to bat for a longer time on a good pitch.

"In Test matches you are always trying to bat for longer periods but in one-day cricket the situation changes all the time."
