At first at all, thanks for reading, and also for replying... I have an A1200r, with this firm: (it's trully fast, It's always under the 45% of memory usage when it's waiting... less than the original 25xp (I think that, that was my original firmware)

R532_G_11.00.59P

r532c2_g_11.30.24bpb

I want to know many things, also things i've never seen in any post...

1- How could i fix my battery indicator, there's any way to show the real percentage? (for example, it could be at 100% for hours, and change to 50% or 5% after 10 minutes playing music at real player, or playing games, etc...)
2- My real player, doesn't refresh, when it goes to 34 or 36% (always diferent), it quits, I only have 300 or 400 songs in a 1gb (kingston card), so the 500 limits is not exceded...it only works when it not inside the card...
3- the rockbox battery indicator doesn't work at all, it changes every second, i have change it in the battery menu as a 850mA, but doesn't do anything. How could i fix it?
4- I have opera as a browser (like everyone), does any way to download a thing? (for example the shockwave player or flash player), It has no place to save to things...there's any way to modificate that? other browser who accept that? and flash?
5- Youtube videos? (stream) is there anyway to see with A1200? I saw some java app, for eg minitube.jar utube.jar but I couldn't make it work.
6- I have been reading other linux's phones forums and i've seen that it's posible to make a swap partition...does anyone tryed that? is it faster than a swap file of the same size?
7- I've a problem with the signal, I enter to some places, for example there's 2 classrooms at the university, that i can't get a line in the signal indicator, but if i restart the phone it works fine, how could I fix it? is it common in this cellphone? my friend, who has the same model, has the same problem (has another firmware)?
8- I don't know if it's a problem or normal in this model, when I calibrate the stylus, i do it almost normally, but when it gets the center cross and last, it take more time to save the position of the stylus...(many times it freezes, normal?), is it normal, that the point it upper than the stylus (you could notice how is your stylus configuration at Drawing, draw a line and see how bad is your configuration)
9- How could I make visible all folders in the card? and how could I modify (permanently) some files inside my phone? (I usually edit those files with the rockbox, but is not so easy to rename files...(eg. .system folder appears at rockbox..)
10- How could I make VR work in this firm(it doesn't speak my messages), I use the spanish language (I speak spanish)? what do I have to modify? what if I erase some other language files, will I have more cellphone space available?
11- there's any chances to modify all the content of my phone? (every file or folder), for example mounting (how? I just don't know much of Linux)
12-Talking again partitions, could I make some partition In my card? For example to Put inside all my media...Type? Sizes? Logical? etc..If it reads the parttions, could I have a bigger card capacity, for example 4gb or 8gb partioned?
13- May have animated gif as background wallpaper? (like most of nokia or sony ericsson...)
14- And java menues? Like sony ericsson (for example -w710, I had one - look in google to see what I'm talking about).
15- There's anyway to add or modify the items in the menu when the cell is closed? (in my menu only appears the Real Player, the camera, only for photos) things to add: for example, the last calls, camera also for video, rockbox with the same things as real (next, back, stop, pause, volume with side buttons, etc...).

Well by the moment it's only that I could remember, I hope that someone could reply at least one of my questions...(just for a start), thanks for replying and thanks for reading my not-so-good english (I speak spanish!)
