K800i debranding question

Hi all,

I was thinking of debranding the phone.
Which is better?

1.Upgrade to K810 firmware K810_R8BA024
2.Upgrade to K800_R8BF003, also what are the new features is there any different to the K810 firmware?
3. Upgrade to a Walkman phone?

Anyone know if there is a way to get the walkman player cos I hate that you can't just press up or down to choose songs but need to go back, enter playlist then select.
Previously I had the w810 and w610 and although I thought the player was pretty simple, it turns out just missing this feature in the k800i is a pain.
But I wanted the better camera so I bought this phone, so you win some you lose some.

Note: I wish SE would make a good walkman and camera phone instead of just one or the other. Anyone know any model that has both good features. Cos most of the walkman phones has a crappy 2mp camera which is not good considering phones are advancing so fast, yet still only put a 2mb camera and only way to get a better cam is to buy Cybershot phones but then you get a crap walkman.

Also can someone explain difference between customisation/cda files and fs file.
How can I backup my network settings, cos then I can put it back in if I want to...cos I got a branded three phone.
Is there a breakloader file I need to flash so I can use far manager?
Also where is the network branding and settings located?

First of all - if you want phone with good camera and walkman look this one - W960i
If you want K800 to K810 here you have tutorial Flash K800 CID53 with K810 software CID53 (for begginers) - Top Sony Forums and you get only TrackID and Photo fix

Than you can't convert this phone to Walkman series for now

is the camera on k810 worse than k800?
I know they are same 3mp but i saw some pics and it looks not as good k800, is it just me?
Also howcome people can't just take the walkman software and put it in there?
it would nice if we could patch it?

===
also I am setting my sights on iphone for my next phone.
pity about the camera which crap - 2mp and no expandable memory.
is it too much to ask for apple to put expandable memory.

also the c905 don't look too bad.

Though I might change brands for my next phone, cos I have been using Sony for a while now, this is my third phone so I might want a change.

also the google phone might be nice, will see.

K800 and k810 have the same camera and drivers.

Have a nice day

but why does the k800i seems to look better in some pics

To me , they look the same.

Have a nice day

in theory due to the camera drivers and hardware capability, they should come out the same.
