Yes, I know replacing the rom is one solution. But it is hard to come by. It's a pity that CAuser's deal has already ended.
There's another one, but the bidding now goes 36 bucks something. I guess the final deal would be around 40, which would be half of the cost of my 728. I want to keep things cheap and use as little as possible to do as much as my 728 can.
Actually I don't mind doing the localization manually. It won't take much space for just one app. The thing is where and how to start.
I used the English UI from Izemise's site. It's very cool but after installing the J freezes a lot
(several times a day
) and it's a tough decision to remove it.
